I have a label form JavaFx to disply if an operation was succeed or not. This should updated automaticaly when the value changed
public class operation {
private BooleanProperty success = new SimpleBooleanProperty();
public final boolean getSuccess() {
return success.get();
}
public final void setSuccess(boolean value) {
success.set(value);
}
public BooleanProperty successProperty() {
return success;
}
}
there is somewhere this code:
operation.setSuccess(true);
and this:
label1.textProperty().bind(Bindings.format("%s", operation.successProperty() != null || false? "succeed": "not succeed" ));
The Problem successProperty() is not value and if I invoke getValue() it will not updated on UI
Your condition never changes. operation.successProperty() != null just checks whether the reference returned by the method successProperty() is null: it never is.
I think you want
label1.textProperty().bind(Bindings
.when(operation.successProperty())
.then("succeed")
.otherwise("not succeed"));

Customized decimal type field generates error after being published.
I've tried many different syntaxes, if isnull(), etc and for some reason I am not thinking to try the right one.
if (tran != null && tran.TranLineNbr != null &&
arTran != null && arTran.TranType == tran.TranType &&
arTran.RefNbr == tran.RefNbr && arTran.LineNbr == tran.TranLineNbr)
{
decimal? amtOrg = arTran.GetExtension<ARTranExt>().UsrDLYAMTORG;
tran.GetExtension<GLTranExt>().UsrDLYAMTORG = amtOrg;
}
The value on release should go from Ar to Gl. All the other custom fields work, but not the decimal.
"Error: An error occurred during processing of the field Original Amount. Specified cast is not valid."
Your data access class should look similar to
/// <summary>
/// Adds extension fields to and modifies attributes in <see cref="ARTran"/>.
/// </summary>
public sealed class ARTranExt : PXCacheExtension<ARTran>
{
public abstract class usrDLYAMTORG : IBqlField
{
}
[PXDBDecimal]
[PXUIField(DisplayName = "Your Field Name")]
[PXDefault(TypeCode.Decimal, "0.00", PersistingCheck = PXPersistingCheck.Nothing)]
public decimal? UsrDLYAMTORG { get; set; }
}
In regards to bringing a custom value from AR to GL on release we have accomplished the same with the following code.
public class ARReleaseProcessExtension : PXGraphExtension<ARReleaseProcess>
{
public delegate GLTran InsertInvoiceDetailsTransactionDel(JournalEntry je, GLTran tran, ARReleaseProcess.GLTranInsertionContext context);
[PXOverride]
public virtual GLTran InsertInvoiceDetailsTransaction(JournalEntry je, GLTran tran, ARReleaseProcess.GLTranInsertionContext context, InsertInvoiceDetailsTransactionDel del)
{
tran.GetExtension<GLTranExt>().UsrDLYAMTORG = context.ARTranRecord.GetExtension<ARTranExt>().UsrDLYAMTORG;
return del?.Invoke(je, tran, context);
}
}
I have created a custom RecordReader for a mapreduce job
class PatternRecordReader extends RecordReader<LongWritable, Text> {
#Override
public boolean nextKeyValue() {
try {
final String value = someParsingLogic();
final boolean hasValue = value != null;
if (hasValue) {
someLogic();
}else{
// I would like to increment a counter here
// something like context.getCounter(Counters.INVALID_INPUT).increment(1);
}
return hasValue;
}
I would like to increment a counter if no value is returned and be able to set it in the Task context, so that it would be accessible by the job.
Is there anyway to achieve this ?
I have a method I need to refactor, as F.Promise has been deprecated in Play 2.5. It's pretty readable actually. It sends a request and authenticates via a custom security token and returns true if the response is 200.
public boolean verify(final String xSassToken){
WSRequest request = WS.url(mdVerifyXSassTokenURL)
.setHeader("X-SASS", xSassToken)
.setMethod("GET");
final F.Promise<WSResponse> responsePromise = request.execute();
try {
final WSResponse response = responsePromise.get(10000);
int status = response.getStatus();
if(status == 200 ) { //ok
return true;
}
} catch (Exception e) {
return false;
}
return false;
}
First thing I had to do was change this line:
final F.Promise<WSResponse> responsePromise = request.execute();
To this:
final CompletionStage<WSResponse> responsePromise = request.execute();
However, CompletionStage(T) doesn't have an equivalent get() method so I'm not sure the quickest and easiest way to get a WSResponse that I can verify the status of.
Yes, it does not. At least not directly.
What you are doing is "wrong" in the context of PlayFramework. get is a blocking call and you should avoid blocking as much as possible. That is why WS offers a non blocking API and a way to handle asynchronous results. So, first, you should probably rewrite your verify code to be async:
public CompletionStage<Boolean> verify(final String xSassToken) {
return WS.url(mdVerifyXSassTokenURL)
.setHeader("X-SASS", xSassToken)
.setMethod("GET")
.execute()
.thenApply(response -> response.getStatus() == Http.Status.OK);
}
Notice how I'm using thenApply to return a new a java.util.concurrent.CompletionStage instead of a plain boolean. That means that the code calling verify can also do the same. Per instance, an action at your controller can do something like this:
public class MyController extends Controller {
public CompletionStage<Result> action() {
return verify("whatever").thenApply(success -> {
if (success) return ok("successful request");
else return badRequest("xSassToken was not valid");
});
}
public CompletionStage<Boolean> verify(final String xSassToken) { ... }
}
This way your application will be able to handle a bigger workload without hanging.
Edit:
Since you have to maintain compatibility, this is what I would do to both evolve the design and also to keep code compatible while migrating:
/**
* #param xSassToken the token to be validated
* #return if the token is valid or not
*
* #deprecated Will be removed. Use {#link #verifyToken(String)} instead since it is non blocking.
*/
#Deprecated
public boolean verify(final String xSassToken) {
try {
return verifyToken(xSassToken).toCompletableFuture().get(10, TimeUnit.SECONDS);
} catch (Exception e) {
return false;
}
}
public CompletionStage<Boolean> verifyToken(final String xSassToken) {
return WS.url(mdVerifyXSassTokenURL)
.setHeader("X-SASS", xSassToken)
.setMethod("GET")
.execute()
.thenApply(response -> response.getStatus() == Http.Status.OK);
}
Basically, deprecate the old verify method and suggest users to migrate to new one.
I am trying to use a library for showing Flash Messages https://github.com/elpete/flashmessage But I am having trouble getting it working correctly. The documentation isn't that great and I am new to ColdFusion. I want to have the ability to have persistent error messages across pages. Specifically during checkout so when the user needs to go back or a validation error occurs the message will appear. According to the documentation:
The FlashMessage.cfc needs three parameters to work:
A reference to your flash storage object. This object will need
get(key) and put(key, value) methods. A config object with the
following properties: A unique flashKey name to avoid naming
conflicts. A reference to your containerTemplatePath. This is the view
that surrounds each of the individual messages. It will have
references to a flashMessages array and your messageTemplatePath. A
reference to your messageTemplatePath. This is the view that
represents a single message in FlashMessage. It will have a reference
to a single flash message. The name is chosen by you in your container
template. Create your object with your two parameters and then use it
as normal.
I am getting the error
the function getMessages has an invalid return value , can't cast null value to value of type [array]
I had this script somewhat working at one point but it seems very finicky. I believe it is my implementation of it. I am hoping someone here can help me figure out where I went wrong. Or give me some pointers because I am not sure I am even implementing it correctly.
This is What I have in my testing script:
<cfscript>
alertStorage = createObject("component", 'alert');
config = {
flashKey = "myCustomFlashKey",
containerTemplatePath = "/flashmessage/views/_templates/FlashMessageContainer.cfm",
messageTemplatePath = "/flashmessage/views/_templates/FlashMessage.cfm"
};
flash = new flashmessage.models.FlashMessage(alertStorage, config);
flash.message('blah');
flash.danger('boom');
</cfscript>
And inside of alert.cfc I have:
component {
public any function get(key) {
for(var i = 1; i < ArrayLen(session[key]); i++) {
return session[key][i];
}
}
public any function put(key, value) {
ArrayAppend(session.myCustomFlashKey, value);
return true;
}
public any function exists() {
if(structKeyExists(session,"myCustomFlashKey")) {
return true;
} else {
session.myCustomFlashKey = ArrayNew();
return false;
}
}
}
The Flash Message Component looks like this:
component name="FlashMessage" singleton {
/**
* #flashStorage.inject coldbox:flash
* #config.inject coldbox:setting:flashmessage
*/
public FlashMessage function init(any flashStorage, any config) {
instance.flashKey = arguments.config.flashKey;
singleton.flashStorage = arguments.flashStorage;
instance.containerTemplatePath = arguments.config.containerTemplatePath;
instance.messageTemplatePath = arguments.config.messageTemplatePath;
// Initialize our flash messages to an empty array if it hasn't ever been created
if (! singleton.flashStorage.exists(instance.flashKey)) {
setMessages([]);
}
return this;
}
public void function message(required string text, string type = "default") {
appendMessage({ message: arguments.text, type = arguments.type });
}
public any function onMissingMethod(required string methodName, required struct methodArgs) {
message(methodArgs[1], methodName);
}
public any function render() {
var flashMessages = getMessages();
var flashMessageTemplatePath = instance.messageTemplatePath;
savecontent variable="messagesHTML" {
include "#instance.containerTemplatePath#";
}
setMessages([]);
return messagesHTML;
}
public array function getMessages() {
return singleton.flashStorage.get(instance.flashKey, []);
}
private void function setMessages(required array messages) {
singleton.flashStorage.put(
name = instance.flashKey,
value = arguments.messages
);
}
private void function appendMessage(required struct message) {
var currentMessages = getMessages();
ArrayAppend(currentMessages, arguments.message);
setMessages(currentMessages);
}
}
My TestNG test implementation throws an error despite the expected value matches with the actual value.
Here is the TestNG code:
#Test(dataProvider = "valid")
public void setUserValidTest(int userId, String firstName, String lastName){
User newUser = new User();
newUser.setLastName(lastName);
newUser.setUserId(userId);
newUser.setFirstName(firstName);
userDAO.setUser(newUser);
Assert.assertEquals(userDAO.getUser().get(0), newUser);
}
The error is:
java.lang.AssertionError: expected [UserId=10, FirstName=Sam, LastName=Baxt] but found [UserId=10, FirstName=Sam, LastName=Baxt]
What have I done wrong here?
The reason is simple. Testng uses the equals method of the object to check if they're equal. So the best way to achieve the result you're looking for is to override the equals method of the user method like this.
public class User {
private String lastName;
private String firstName;
private String userId;
// -- other methods here
#Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (!User.class.isAssignableFrom(obj.getClass())) {
return false;
}
final User other = (User) obj;
//If both lastnames are not equal return false
if ((this.lastName == null) ? (other.lastName != null) : !this.lastName.equals(other.lastName)) {
return false;
}
//If both lastnames are not equal return false
if ((this.firstName == null) ? (other.firstName != null) : !this.firstName.equals(other.firstName)) {
return false;
}
//If both lastnames are not equal return false
if ((this.userId == null) ? (other.userId != null) : !this.userId.equals(other.userId)) {
return false;
}
return true;
}
}
and it'll work like magic
It seems you are either comparing the wrong (first) object or equals is not correctly implemented as it returns false.
The shown values are just string representations. It doesn't actually mean that both objects have to be equal.
You should check if userDAO.getUser().get(0) actually returns the user you are setting before.
Posting the implementation of User and the userDAO type might help for further clarification.
NOTE: Note directly related to this question but it's answer to my issue that got me to this question. I am sure more ppl might end-up on this post looking for this solution.
This is not precisely the a solution if Equals method needs overriding but something that I very commonly find myself blocked due to:
If you have used Capture and are asserting equality over captured value, please be sure to get the captured value form captured instance.
eg:
Capture<Request> capturedRequest = new Capture<>();
this.testableObj.makeRequest(EasyMock.capture(capturedRequest))
Assert.assertEquals(capturedRequest.getValue(), expectedRequest);
V/S
Assert.assertEquals(capturedRequest, expectedRequest);
while the compiler wont complain in either case, the Assertion Obviously fails in 2nd case
