GWTP Nested Presenter Issue
When using GXT with gwtp framework the nested presenters are not displayed. However the html is attached to the DOM. Only doing resize or calling Container's forceLayout() displays the content.
This happens when using GXT container (VBoxLayoutContainer) as a top-level container for nested presenter. When using native GWT panel like FlowPanel the presenter is displayed after onReveal() event without the need to resize or forcing layout.
I would appreciate any help.
