I am having an issue with a growing list. Previously I had a normal list, but as it is limited to displaying 100 items, I need to now change this to a growing list, which works fine now and I can get over 100 items loaded when I've put the growing="true" growingThreshold="50" growingScrollToLoad="false" properties on the list.
But now I have an issue with one of the number inputs in the custom list, when entering a number it is not staying set (it has a liveChange event that updates a text component).
I've set a breakpoint in the controller to test and it seems to bug out when I am trying to set the data changes (red arrow on attached image).
Can anyone see the issue with the logic? If any additional code snippets are required I could provide them.
onReceivedQuantityChange: function (oEvent) {
// get model and data
var oModel = this.getOrderModel();
var oData = oModel.getData();
// get item from path
var oItem = this._getOrderItemByPath(oEvent.getSource().getBindingContext(this.MODEL_ORDERS).getPath());
// set received value
oItem._ReceivedValue = oEvent.getParameters().newValue * (oItem.ValuationPrice / oItem.Quantity);
// apply data changes
oModel.setData(oData);
},
Controller code image
onReceivedQuantityChange: function (oEvent) {
var oModel = this.getOrderModel()
var sItemPath = oEvent.getSource().getBindingContext(this.MODEL_ORDERS).getPath()
var iValuationPrice = oModel.getProperty(sItemPath + '/ValuationPrice')
var iQuantity = oModel.getProperty(sItemPath + '/Quantity')
var iNewValue = oEvent.getParameters().newValue
var iReceivedValue = iNewValue * (iValuationPrice / iQuantity)
oModel.setProperty(sItemPath + '/_ReceivedValue', iReceivedValue)
}
If you use setProperty() on the Model you're only chaning the specific Property in DataModel and Sapui5 is able to proceed bindingchanges on this Property only (and not the whole model).
If you get the data out of the model by getData() you are only getting a reference to this Object. If you change something on this Object, you don't have to set it back by setData() (it is already there because you used the reference of this Object).
But Sapui5 need to know that there was a specific change in datamodel and this is done by using setProperty()

I am working with O365 SharePoint Online platform with SharePoint lists around 300 items in All Items View. For the first 30 items Text to Html Javascript function successfully converts text code to Html and displays status in HTML color format, but when I am trying to select next 31 items and go ahead using the pagination the function does not able to convert Html and display only text codes. I also changed the calculated column value type to "Number" to get the HTML to render in the list view. But not being changed yet. Does anyone please who have the code handy to make this work easy? Below is the Text to HTML code used in O365 platform.
<script type="text/javascript">
function TextToHTML(NodeSet, HTMLregexp) {
var CellContent = "";
var i=0;
while (i < NodeSet.length){
try {
CellContent = NodeSet[i].innerText || NodeSet[i].textContent;
if (HTMLregexp.test(CellContent)) {NodeSet[i].innerHTML = CellContent;}
}
catch(err){}
i=i+1;
}
}
// Calendar views
var regexpA = new RegExp("\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*");
TextToHTML(document.getElementsByTagName("a"),regexpA);
// List views
var regexpTD = new RegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
TextToHTML(document.getElementsByTagName("TD"),regexpTD);
// This function is call continuesly every 100ms until the length of the main field changes
// after which the convert text to HTML is executed.
//
var postElemLength = 0;
function PostConvertToHtml()
{
if (postElemLength == document.getElementsByTagName("TD").length)
{
setTimeout(PostConvertToHtml,100);
}
else
{
var regexpTD = new RegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
TextToHTML(document.getElementsByTagName("TD"),regexpTD);
}
}
// Grouped list views
ExpGroupRenderData = (function (old) {
return function (htmlToRender, groupName, isLoaded) {
var result = old(htmlToRender, groupName, isLoaded);
var regexpTD = new RegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
TextToHTML(document.getElementsByTagName("TD"),regexpTD);
// start the periodic callback to check when the element has been changed
if(isLoaded == 'false')
{
postElemLength = document.getElementsByTagName("TD").length;
setTimeout(PostConvertToHtml,100);
}
};
})(ExpGroupRenderData);
// Preview pane views
if (typeof(showpreview1)=="function") {
showpreview1 = (function (old) {
return function (o) {
var result = old(o);
var regexpTD = new RegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");

Assuming you are using the Classic UI in SharePoint Online...
Two possible issues:
Check to see if the site has the Minimal Download Strategy enabled.
If so disable it and test your code. MDS often is the cause for JavaScript running only once. (The page is not reloaded, only the data area.)
The loading of the next page of the list is via a Web Service call and that may not be triggering your JavaScript. (Again, the page is not reloaded, only the data area.) You may need to intercept the paging link to insure your code is run. (Also check to see if the "Asynchronous Load" option has been enabled. Edit the page, edit the web part, and expand the "AJAX Options" section.)
You may want to take a look at a workflow plus a Calculated column solution to add the color coding. See: http://techtrainingnotes.blogspot.com/2018/01/adding-html-to-sharepoint-columns-color.html
For a Tag model that I have in Ember-Data, I have 4 records in my store:
Tags:
id tag_name
1 Writing
2 Reading-Comprehension
3 Biology
4 Chemistry
In my code I have an array of tag_names, and I want to get a corresponding array of tag IDs. I'm having 2 problems:
My server is being queried even though I have these tags in my store. When I call store.find('tag', {tag_name: tag_name}), I didn't expect to need a call to the server. Here is all the code I'm using to attempt to create an array of IDs.
var self = this;
var tagsArray = ["Writing", "Reading-Comprehension", "Chemistry"];
var tagIdArr = []
tagsArray.forEach(function(tag_name) {
return self.store.find('tag', { tag_name: tag_name }).then(function(tag) {
tagIdArr.pushObject(tag.get('content').get('0').get('id'));
})
})
return tagIdArr;
When I console.log the output of the above code gives me an empty array object with length 0. Clicking on the caret next to the empty array shows three key-value pairs with the correct data. But the array is empty. I'm sure there is a simple explanation for this behavior, but I'm not sure why this is. I've used code similar to the above in other places successfully.
Find hits the server, but peek does not.
var tagsArray = ["Writing", "Reading-Comprehension", "Chemistry"];
return this.store.peekAll('tag').filter(function(tag){
return tagsArray.indexOf(tag) !== -1;
}).mapBy('id');

Can a Date.now type function be used in either map or reduce functions? Can it be used anywhere at all?
More specifically, the view must not cache the Date.now value.
Here is what I tested that only worked for the first run after a change to any view function:
function (doc){
var n = new Date();
if(doc.TimeStamp > n.getTime() - 30000){
emit(doc._id, doc);
}
}
The view rows will be refreshed only when the particular doc gets updated. But you can request the view for that result: emit the doc.TimeStamp as key and request the view with ?startkey=timestamp where timestamp is the value of now.getTime() - 30000.
Yes. var now = new Date() should work.
The condition must result in false. You can test it with the view:
function (doc) {
var now = new Date()
var timestamp = now.getTime()
emit(timestamp,null)
}
It will respond something like
{
"total_rows":1,
"offset":0,
"rows" :[{
"id":"ecd99521eeda9a79320dd8a6954ecc2c",
"key":1429904419591, // timestamp as key
"value":null
}]
}
Make sure that doc.TimeStamp is a number (maybe you have to execute parseInt(doc.TimeStamp)) and greater then timestamp - 30000
Two words about your line of code emit(doc._id, doc);:
To emit doc._id as key means maybe you doesn't need the view. Simply request the doc by GET /databasename/:id. Also to include doc._id in multipart keys or the value of the view row is mostly not necessary because its included in every row automatically as additional property. One valid reason would be when you want to sort the view over the doc ids.
To emit the doc as value is not recommended for performance reasons of the view. Simply add ?include_docs=true when you request the view and every row will have an additional property doc with whole doc in it.
My problem is how to ensure that no data will be lost while concurrent access.
I have script published as web-app. I want to add new row to DATA_SHEET. The function that handles submit button looks like this:
function onButtonSubmit(e) {
var app = UiApp.getActiveApplication();
var lock = LockService.getPublicLock();
while (! lock.tryLock(1000))
;
var ssheet = SpreadsheetApp.openById(SHEET_ID);
var sheet = ssheet.getSheetByName(DATA_SHEET);
var lastRow = sheet.getLastRow();
var lastCol = sheet.getLastColumn();
var rangeToInsert = sheet.getRange(lastRow+1, 1, 1, lastCol);
var statText = rangeToInsert.getA1Notation();
rangeToInsert.setValues(<some data from webapp form>);
app.getElementById('statusLabel').setText(statText);
lock.releaseLock();
return app;
}
But it seems that this does not work. When I open two forms and click submit button within one second, it shows same range in statsLabel and writes data into same range. So I lose data from one form.
What is wrong with this code? It seems like tryLock() does not block script.
Is there any other way how to prevent concurrent write access to sheet?
It might be worth taking a look at appendRow(), rather than using getLastRow()/setValues() etc.
Allows for atomic appending of a row to a spreadsheet; can be used
safely even when multiple instances of the script are running at the
same time. Previously, one would have to call getLastRow(), then write
to that row. But if two invocations of the script were running at the
same time, they might both read the same value for getLastRow(), and
then overwrite each other's values.
while (! lock.tryLock(1000))
;
seems a bit hinky. Try this instead:
if (lock.tryLock(30000)) {
// I got the lock! Wo000t!!!11 Do whatever I was going to do!
} else {
// I couldn’t get the lock, now for plan B :(
GmailApp.sendEmail(“admin#example.com”, “epic fail”,
“lock acquisition fail!”);
}
http://googleappsdeveloper.blogspot.com/2011/10/concurrency-and-google-apps-script.html
You must insert this code when using getLastRow()/setValues() with lock.
SpreadsheetApp.flush();
// before
lock.releaseLock();
I have a "Featured" widget to lead visitors to items I want to feature on certain pages. So I'm trying to get Alex Shyba's Advanced Database Crawler for Sitecore to return all the items that refer to the context item. If I put in one template ID, it works fine. But if I pipe delimit the two templates, I never get a result. What am I doing wrong?
var searchParam = new MultiFieldSearchParam()
{
Database = Sitecore.Context.Database.Name,
Language = Sitecore.Context.Language.Name,
TemplateIds = "{E5B41848-3C07-4F17-84A5-C2C29AD43CAE}|{0C2E35D7-C4C9-478B-B4AB-DE8C2A00908B}"
};
var refinements = new List<MultiFieldSearchParam.Refinement>();
refinements.Add(new MultiFieldSearchParam.Refinement("pages", contextItemGUID));
searchParam.Refinements = refinements;
var runner = new QueryRunner("web");
foreach (var skinnyItem in runner.GetItems(searchParam))
{
yield return skinnyItem.GetItem();
}
Again, if I make that TemplateIds a single GUID (either one), it works as expected, but just returning, obviously, items of the specified template.
As Mark notes, it's a bug in the ADC. Our solution was to refactor the ApplyTemplateFilter method as follows:
protected void ApplyTemplateFilter(CombinedQuery query, string templateIds, QueryOccurance occurance)
{
ApplyIdFilter(query, BuiltinFields.Template, templateIds, occurance);
}
