I am trying to perform a check on the client side (my browser), before processing the content of the input field on the server side using the RAP application.
I set up a HelloWorld example for the application using the RAP developes-guide documentation (cannot upload the link from the external sites) and then I removed all components and add a simple text field. For the next step, I created a javascript file and inject it using scripting documentation for RAP.
Now when I run RWT Application for BasicEntryPoint, the listener is added to a text field, with the comment in a javascript file ("//# sourceURL=test.js", also tried with @ instead of #), and when I open the developer tools on my browser, the script is not in sources and therefore I am unable to debug. The goal of the script is to check if the key pressed by the user is an 'a' character, if yes, skip that character.
In addition I will upload my BasicEntryPoint.java file and javascript file.
Any help would be appreciated!

Hi Aleksandar,
I think there must be no extra quotes around the sourceURL comment. I see "test.js" in the sources when I use the sourceURL comment without quotes. About the event handling: According to the js docs [1], there is no field event.key. You could check the field event.character instead and set the field event.doit accordingly. This worked for me:
@Override
protected void createContents(final Composite parent) {
final Text text = new Text(parent, SWT.BORDER);
GridDataFactory.fillDefaults().grab(true, false).applyTo(text);
String scriptCode = "//# sourceURL=test.js\n";
scriptCode += "const handleEvent = event => event.doit = event.character !== 'a';";
text.addListener(SWT.KeyDown, new ClientListener(scriptCode));
}
Regards,
Sebastian
