Created attachment 287760 [details] simple html that invokes a BrowserFunction In this simple example, there are three identical browsers. Each with a html button that sends some dummy data to BrowserFunction. They all work fine. If I launch a second instance of the same app. The browser and html shows up but no BrowserFunction is ever triggered. I first noticed this problem in a more complex app where there are multiple JFace Dialogs showing at the same time, each with an Edge browser. This is only a problem in Edge/WebView2 implementation. The same code works on OSX and Windows IE 11 mode.

Hi! Expiriencing the same issue. Could anybody advice is there any solutions or workaround for that issue?
Please try: browser.getDisplay().asyncExec(()->{ final File testFile = new File(EdgeBrowserTest.class.getResource("EdgeBrowserTest.html").toURI()); browser.setUrl(testFile.toURI().toString()); }); instead of calling browser.setUrl(..) directly after registering the BrowserFunction. That seems to cure the problem in our code at least.
Tried the workarround proposed but was not successfull for us :( Our usage is a browser within a specialized EcoreEditor, we encounter the same bad behavior: first tab work perfect, second open tab start withoyut having any BrowserFunction loaded.
My team managed to get the issue resolved by setting the BrowserFunction inside ProgressAdapter#completed(). See example below (commented out code was before changes): public EdgeUpliftBrowserWindow(Shell parent) { // Browser browser = new Browser(parent, SWT.EDGE); // new OpenTestWindow(browser); // browser.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true)); // browser.setUrl(HTML_RESOURCE); Browser browser = new Browser(parent, SWT.EDGE); browser.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true)); browser.addProgressListener(new ProgressAdapter() { @Override public void completed(ProgressEvent event) { new OpenTestWindow(browser); } }); browser.setUrl(HTML_RESOURCE); } private final class OpenTestWindow extends BrowserFunction { public OpenTestWindow(Browser browser) { super(browser, "openTestWindow"); //$NON-NLS-1$ } @Override public String function(Object[] arguments) { System.out.println("Function Has Been Called!"); //$NON-NLS-1$ return null; } }
