IE: Page disappears on rollover (hover)

[kevboy]

Everything displays fine in Firefox 3.6.13 and Chrome 8. However, in IE7, everything displays fine until I hover (rollover) a button or something that has a rollover state. The whole page disappears (turns white) after that. I see in the log that the rollover image gets download but nothing else.

Things I've tried but didn't work:
* Recompiled
* Deployed on GWT tomcat server and Weblogic
* Cleared my browser settings and cache
* Remove GWT Development Plug-in
* GWT hosted/development mode and non-hosted mode
* Developer console set to debug didn't show anything either
* Different versions of SmartGWT: 2.3-2010-9-28 and 2.4-2010-12-21

I'm running out of things to try. Any other pointers?

See the FAQ on DocType and if that doesn't help post a minimal standalone testcase. It does not happen in the showcase and others haven't reported this kind of behavior.

Thanks for the pointers. However, we couldn't find anything that helped this issue. We've narrowed it down to buttons in a toolstrip and tab headers though.

After searching, I found out it might be similar to this problem:

The solution to this problem was to call Canvas.draw() on the toolstrip. I tried this and the toolstrip appears at the top of the page.

We have been using Layout.setMembers(toolstrip, ... ) to set the location of the toolstrip. How would we place the toolstrip inside another Canvas using Canvas.draw()?

In general, call draw() to draw the entire widget hierarchy (just once, on the top-level component). Do not use RootPanel.add() to add widgets.

Make sure you've read the QuickStart Guide front to back - this is in there.

I just posted to the other thread and it was exactly what you mention. I believe the RootPanel.add() was a relic of starting with Google's tutorial on GWT instead of SmartGWT's QuickStart Guide. Thanks!
