Coldfusion app generating blank PDF page - coldfusion

We had a server migration and since the migration, a Coldfusion application is generating blank pdf pages that are able to be saved locally and printed. The application queries a SQL Server database. I have been through the code several times and am pretty positive the data sources are all pointed to the new environment. I have a report from the day before the migration and all was well. I think the paths are fine because when I changed the path, the application blew up. I have minimal experience with Coldfusion and I am out of ideas at the moment. What else should I be looking at when debugging this application? Has any code been deprecated and the new environment will not run it? Is it possible there are settings on the new server preventing this PDF from being generated? Do I need to add a MIME somewhere that was unnecessary before? Any advice would be helpful. Below is some of the code being used.
<cfif #qSelect.Record# EQ 0>
<h1>Empty recordset</h1>
<cfelse>
<cfdocument filename="../Reports/CustomReport.pdf" format = "pdf" orientation = "landscape" overwrite="yes">
<h2>Database</h2>
<cfoutput>
<h4>Monthly Report </h4>
</cfoutput>
<table cellpadding="3" cellspacing="0" border="0">
<tr>
<th>Date</th>
<th>Status</th>
</tr>
<cfoutput query="qLocalEvents">
<tr>
<td>#DateFormat(qSelectEvents.EventDate, "mm/dd/yyyy")#</td>
<td>#qSelectEvents.Status#</td>
</tr>
</cfoutput>

Coldfusion creating reports with wkhtmltopdf

I am trying to get some assistance with wkhtmltopdf.
I have downloaded and installed and trying to get it to work correctly with my program.
What I have is a form that lets the user choose print, preview or excel. When the user chooses print I want pop up the html table that is created by a query depending on the associates and locations that are chosen.
Right now when the user chooses print it just shows this table in the browser.
<cfif FORM.Format IS "print">
<!---<cfdocument format="pdf" scale="75" backgroundvisible="yes" overwrite="no" fontembed="yes">--->
<link rel="stylesheet" href="css/form-table.css"/>
<!---<cfdocumentitem type="header" >
<cfoutput><p align= "right">Page #cfdocument.currentpagenumber# of #cfdocument.totalpagecount#</p></cfoutput>
</cfdocumentitem> --->
<div class="RTable">
<h3 class="RTable-h3">CHECKLIST STATS</h3>
<cfoutput>
<ul class="RTable-headingList">
<li>FROM <span class="RTable-headingList-date">#dateFormat(date1, 'mm/dd/yyyy')#</span> TO <span class="RTable-headingList-date">#dateFormat(date2, 'mm/dd/yyyy')#</span></li>
<li>LOCATIONS: <span class="RTable-headingList-locations">#locList#</span></li>
</ul>
</cfoutput>

I am trying to use it like cfdocument in the <cfif FORM.Format IS "print"> do I cfexecute this table some how in replace of how I have the table? I am using this as reports and dont want to save a million reports to the server. I guess I am looking for some assistance in getting off on the right foot. Any help would be greatly appreciated.
Iv tried adding this code inside the if "print":
<cfexecute name="C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe"
arguments="http://path/path/checklist/wkhtmltestpage.cfm C:\temp\wkhtmlTest.pdf"
errorVariable="errorMessage"
timeout="10"
/>
But this does not download it to show the user to print.
Also for some reason its not going to the link I am specifying its making a pdf of the login page...
When WKHTMLTOPDF requests the webpage, the "user" is not authenticated and the CGI.Http_User_Agent contains "wkhtmltopdf". The remote IP of the request will also be a local IP that is configured on the server. As a result, I don't directly process any CFM scripts using WKHTMLTOPDF.
I recommend:
Use CFContent to capture generated static HTML.
Save the HTML to a public-accessible directory with a random file name.
Use the web path + random file name w/WKHTMLTOPDF command line.
After PDF is generated, delete random files.
This process will make any issues easier to troubleshoot. I prefer creating static BAT files with the same randomized filename so that I can manually re-run on the server or even locally on my on PC to further troubleshoot and view any weird messages returned by the program. There's many other command line settings you'll want to pass (margins, orientation, pagesize, header/footer, JS delay, etc), so creating a standalone BAT file with all of the command line arguments is the best approach. (I noticed in another question that you may be using CFX_Exec. I recommend using it over CFExecute.)
<!--- Simple WKHTMLTOPDF Generation Usage --->
<cfset FileID = CreateUUID()>
<cffile action="WRITE" file="#webroot#\#FileID#.htm" output="#TheHTML#">
<cfexecute name="C:\wkhtmltopdf.exe" arguments="http://mywebsite.com/#FileID#.htm C:\temp\#FileID#.pdf" timeout="30">
<cffile action="DELETE" file="#webroot#\#FileID#.htm">
To deliver the PDF file, you can either perform a 302 redirect to the randomized PDF file and let your webserver handle the mimetype (and then delete it later) or use CFContent to deliver it using a ColdFusion thread and automatically delete it:
<!--- Return PDF to browser inline or as downloadable attachment --->
<!--- <cfheader name="content-disposition" value="attachment; filename=""NiceFilename.pdf"""> --->
<cfheader name="content-disposition" value="inline; filename=""NiceFilename.pdf""">
<cfcontent type="application/pdf" file="C:\temp\#FileID#.pdf" deletefile="Yes">

how to insert single checkbox value in coldfusion code

I have a single checkbox, I want that when I check the checkbox it
should insert 1 else 0 in the database. How can I do that? This was
earlier a radio button field which is getting converted to check box so
already entry in the database is working good, I am posting my database
code as well.
<tr>
<td class="leftFormLabelCell extrasmalltextbold" style="border-
left:1px solid ##9c9c9c;" width="15%">
#mocTrans.Translate("Required template Action Item?")#
</td>
<td>
<input type="checkbox" name="reqtempactionitem" value="0">
</td>
</tr>
Databse code:
<cfif StructKeyExists(URL, "reqtempactionitem") and
IsBoolean(URL.reqtempactionitem)>
, #reqtempactionitem#
<cfelse>
, 0
</cfif>
The way html checkboxes work is that if checked, the browser will submit [checkboxname]=[value] to the webserver. If the box is not checked, the browser does not submit anything at all to the server.
So the easiest solution uses cfparam, which will give the submitted checkbox a default value.
Thus, in your html, you should have:
<input type="checkbox" name="reqtempactionitem" value="1">
(As has been noted in comments, your value was 0 and should be 1.)
Then, in the database code:
<cfparam name="reqtempactionitem" default="0">
...
dbfield = <cfqueryparam cfsqltype="cf_sql_bit" value="#reqtempactionitem#">
Note the use of cfqueryparam, which is strongly recommended in all queries for both performance and security reasons.

cfdocument issue - cfdocument has no body

I am working with Coldfusion10 and am facing this error:
The following information is meant for the website developer for debugging purposes.
Error Occurred While Processing Request
cfdocument tag has no body.
It must have a body or a source file or URL.
I checked the website and detected that cfsettings is not defined at the top or anywhere which can cause this issue, I am using it as
<cfdocument format="pdf">
<cfdocumentsection>
<cfdocumentitem type="header"></cfdocumentitem> - Footer is used too
</cfdocumentsection>
I tried using evalAtPrint= true but still no success. Am I missing something here?
Make sure you are actually putting in at the end. I'm assuming you just missed this here.
Otherwise everything seems to align up with the Wiki Docs.
I would suggest two things.
Verify you are using ColdFusion 11 Update 3. Update 3 was a major update and may have addressed this issue.
If you are using update 3, open a bug at bugbase.adobe.com
The error message you included in your question indicates that there is no content between your <cfdocument> tags. The code that you included corroborates that. If this is not your actual code then we cannot be of much help.
You need to include the content that you would like to be converted into PDF between the <cfdocument> tags. You need something like this:
<cfquery datasource="cfdocexamples" name="empSalary">
SELECT Emp_ID, firstname, lastname, e.dept_id, salary, d.dept_name
FROM employee e, departmt d
WHERE e.dept_id = d.dept_id
ORDER BY d.dept_name
</cfquery>
<cfdocument format="PDF">
<cfoutput query="empSalary" group="dept_id">
<cfdocumentsection>
<cfdocumentitem type="header">
<font size="-3"><i>Salary Report</i></font>
</cfdocumentitem>
<cfdocumentitem type="footer">
<font size="-3">Page #cfdocument.currentpagenumber#</font>
</cfdocumentitem>
<h2>#dept_name#</h2>
<table width="95%" border="2" cellspacing="2" cellpadding="2" >
<tr>
<th>Employee</th>
<th>Salary</th>
</tr>
<cfset deptTotal = 0 >
<!--- inner cfoutput --->
<cfoutput>
<tr>
<td>
<font size="-1">#empSalary.lastname#, #empSalary.firstname#</font>
</td>
<td align="right">
<font size="-1">#DollarFormat(empSalary.salary)#</font>
</td>
</tr>
<cfset deptTotal = deptTotal + empSalary.salary>
</cfoutput>
<tr>
<td align="right"><font size="-1">Total</font></td>
<td align="right"><font size="-1">#DollarFormat(deptTotal)#</font></td>

<cfset deptTotal = 0>
</table>

Processing ColdFusion variables which reside inside a database table

One of my table is saving an HTML form which contains ColdFusion variables. In my code I am querying this table and need to display this form in the front end. But while displaying I am getting the ColdFusion variable names instead of the values of the variables.
HTML Form saved in the db table:
<form action="" name="ci_entry_form" id="ci_entry_form" method="post">
<table width="100%" height="100%" border="0">
<tr>
<td align="right"><b style="color:red">*</b> <label class="pop_up_letter_font">G/L # :</label></td>
<td> <input class="pop_up_textbox" type="text" name="gl_number_text" id="gl_number_text" maxlength="21" value="#ARGUMENTS.chkDetails.GL_ACCT_NBR#" required/>
<select class="pop_up_dd" name="gl_number_drop" id="gl_number_drop" onChange="enableDisableGL()">
<option value="">---Select---</option>
<option value="new">Enter a new G/L number</option>
<cfoutput query="glNumbers">
<option value="#glNumbers.GL_ACCT_NBR#">#glNumbers.GL_ACCT_NBR#</option>
</cfoutput>
</select>
</td>
</tr>
</table>
</form>
Method (cffunction) contains below code to query this html form from db table and return the html form.
<cfquery name="qry_getTemplate" datasource="#APPLICATION.dsn#">
select FORM_TXT from HTML_FORMS where REQ_ID = 172
</cfquery>
<cfsavecontent variable="form_content">
<cfoutput>#qry_getTemplate.FORM_TXT #</cfoutput>
</cfsavecontent>
But when I dump the cfcontent variable form_content I am getting the HTML Form without processing the coldfusion variables #ARGUMENTS.chkDetails.GL_ACCT_NBR#, #glNumbers.GL_ACCT_NBR#.
Am I missing something? Can any one help me out resolve this?
I'm pretty sure if you searched this site or via Google a bit you could have found the answer to this already posted somewhere, given it comes up all the time (about once every 3-4 months).
You can't output CFML and somehow hope that it will execute.
I've summarised the CFML request / compile / response process on my blog: "The ColdFusion request/response process".
Bottom line: CFML source code needs to be loaded from the file system at compile time not at runtime. So your code needs to be in the file system when you want it to execute, not in the DB or in a variable.
You can write the code to file and then include it, though. This is detailed in that blog article.

cfdocument prevent page breaks mid-row

I know this has been asked before but the solutions are from 2.5+ years ago so I'm asking if anyone has devised or knows of a more elegant solution to the problem using CF9. Can anyone confirm if CF10 supports the "page-break-inside: avoid" rule?
How can I prevent page-break in CFDocument from occuring in middle of content?
COLDFUSION: cfdocument and forcing a pagebreak
This is pretty much how I'm doing it. I've estimated, depending on what type of page it is, I can fit 9 or 11 rows of data before having to force a page break. Of course this is prone to breaking so if anyone knows of any evolution of the solution I would be grateful.
I believe I have found a pseudo solution. It is basically just what I said in the comments above. I take a best guess and see if it fits using the value of cfpdf's getInfo.totalPages. If it fits, great, merge it to the final document, if it doesn't, try again with one less row.
The downside to doing it this way is that it slows it down a bit and you can't use some of the stuff cfdocument makes easy like like messing with headers and footers. That being said, part 2 of this solution may be to record the number of rows that fit on a page in an array instead of merging the pages and rebuild the entire document again using cfdocument and those values as the loop constraints forcing a page break after. As it is, the below solution is already a little time consuming so building it again inside of a cfdocument tag may not work in high traffic sites.
Bug workaround: It looks like there is a bug with cfdocument that removes the background colors when saving the document to memory with the name attribute. The workaround is to remove the cfdocument tag to an external file. I saw one programmer placed it into a cfc, I found it's possible to use a simple cfinclude.
I hope someone finds this helpful, and if you know a better way to do this please comment.

Travis - I don't know of another way to do this. Usually I create an HTML table as the core of each "page" and have a specific number of rows before I close the table, break the page and open a new table.
