Hello,

the modal dialogs functionality of 1.5M5 is awkward.
when either button of the dialog event is called, the dialog disappears, but the modal nature remains, meaning the UI is frozen.

following is the code snippet which uses the message dialog :
final MessageDialog dialog = new MessageDialog(_toolBar.getShell(),
				"Delete Confirmation", null,
				"Do you wish to delete this record [y/n] ?",
				 MessageDialog.QUESTION, new String[] { "Yes", "No", "Cancel" },
				 2);
		final int answer = dialog.open();
		switch (answer) {
		case -1:
			/* no selection provided */
			break;
		case 0:
			/* dialog action - yes */
			final boolean status = runAction(ClientsideActionsContributor.ON_BEFORE_DELETE_RECORD_EVENT);
			if (status) {
				((DatasetController) getDatasetBroadcast())
						.setActionState(BusinessObject.ACTION_DELETE);
				((DatasetController) getDatasetBroadcast()).performDelete();
				refreshRecordAction();
			}
			runAction(ClientsideActionsContributor.ON_AFTER_DELETE_RECORD_EVENT);
			break;
		case 1:
			/* dialog action - no */
			break;
		case 2:
			/* dialog action - cancel */
			break;
		}


the above code snippet did work as expected in 1.4, but with 1.5M5 the dialog's modal behavior remains, even after closing the dialog.

i also have custom dialogs like "SetupCustomEditorDialog" extends the Dialog, which works as expected with modal behavior in 1.5M5. (after closing the dialog, UI become responsive)

also, if i refresh the page while frozen after the dialog, i get the following errors in console :

Hi Sudesh,
I think that you are running into this bug:
370139: [Dialog] Modal dialog blocks application upon close
https://bugs.eclipse.org/bugs/show_bug.cgi?id=370139
Could you attach your test snippet there? A complete self-running
snippet is welcomed.
Thanks,
Ivan

Hello Ivan,

I've found something interesting on this case.
The frozen behavior of the dialog only exist, when calling the dialog using following code snippet :

		_deleteRecordAction.addHyperlinkListener(new HyperlinkAdapter() {
			@Override
			public void linkActivated(final HyperlinkEvent e) {
				if (_deleteRecordAction.isEnabled()) {
					final UIJob job = new UIJob("") {
						@Override
						public IStatus runInUIThread(
								final IProgressMonitor monitor) {
                                                        deleteRecordAction(); // This is the method that invokes the message dialog
							return Status.OK_STATUS;
						}
					};
					job.setUser(true);
					job.schedule();					
				}
			}
		});


if i remove the UIJob and just call the deleteRecordAction(), it works as expected.

Regards,
Sudesh Bulathsinhala

Sudesh,
thanks for your findings. Could you please create a self-running
snippet/project and attach it to the bug?
Thanks,
Ivan

hello Ivan,
i've attached simple project with RAP mail demo to the reported bug - https://bugs.eclipse.org/bugs/show_bug.cgi?id=370139, where Open Message action will trigger the frozen behavior.
