We have a EXT-GWT web application that runs in IE and uses an IFrame to embed an ActiveX Control. In the outer frame, the app creates an EXT Window object and sets the window as modal using the setModel(true) method. The window is shown as a lightbox over the application, but the ActiveX Control in the IFrame disappears. I found the following thread in the forums that discusses a verify similar problem using EXT-JS to mask an area that contains an ActiveX Control: http://www.sencha.com/forum/showthread.php?68270-mask-and-active-X-control. Is there a similar workaround for EXT-GWT Window object that would allow the ActiveX Control to remain visible and operable even though the rest of the app is disable with the lightbox?
You will need to change the source of the El class. Simple to the exact same change as did in that thread in the mask method. You can almost copy and paste the change in bold.
However that wont be help you with your problem probably, because setMask(true) on a window does not use the masking functionality.
Do you have some testcase that implements EntryPoint and shows your problem?
Window.setModal(true) hides ActiveX Control in IE
