I'm using gwt frames linked to external pages inside portlets.
The thing is that each action on the portlet (minimize, maximize, drag and drop etc.) make the frame reload his content which is crippling my application.

Is it a standard behaviour for portlets ? If yes, how to override it ?

To be thorough, i use a workaround to simulate onLoad events on these iframes in order to make them work with IE. Could it be a problem ?
