Memory leak in Dialog

[JohVle]

Hi all,

I think there is a memory leak in the com.extjs.gxt.ui.client.widget.Dialog.

Here is a little test with a button to open a number of dialogs and a button to close them afterwards. Part of the memory is not released when closing the dialogs.

Do I have to call other cleanup methods or should dialog.close() do the job ?

Tested on IE6, FF2 and Chrome with GWT 1.5.2 and Gxt 1.1.2.

public class DialogExampleEntryPoint implements EntryPoint {

	private Dialog[] dialogs;
	private int NUMBER_OF_DIALOGS = 25;

	public void onModuleLoad() {
		LayoutContainer buttonPanel = new LayoutContainer();
		ButtonBar buttons = new ButtonBar();
		buttons.add(new Button("Open Multiple Dialogs",
				new SelectionListener<ComponentEvent>() {
					public void componentSelected(ComponentEvent ce) {
						dialogs = new Dialog[NUMBER_OF_DIALOGS];
						for (int i = 0; i < NUMBER_OF_DIALOGS; i++) {
							dialogs[i] = new Dialog();
							dialogs[i].show();
						}
					}
				}));

		buttons.add(new Button("Close Multiple Dialogs",
				new SelectionListener<ComponentEvent>() {
					public void componentSelected(ComponentEvent ce) {
						for (int i = 0; i < NUMBER_OF_DIALOGS; i++) {
							dialogs[i].close();
							dialogs[i] = null;
						}
						dialogs = null;
					}
				}));

		buttonPanel.add(buttons);
		RootPanel.get().add(buttonPanel);
	}
}

I got the same problem with gxt dialogs and IE6.
Memory increases about 1-4MB each time I open a dialog and close it again. I use CloseAction.CLOSE and only gxt widgets, no DOM manipulation...

Minimizing the browser Window an maximizing again frees most of the memory so I can start again.

Splitting my ImageBundles as suggested here http://groups.google.com/group/Googl...f75010293a16af
helped a lot but seems not to be the only problem
