Ok, I've created a sample that shows the current variation of the problem.
The sample code sets the text of components during tab change.
Relevant for the execution is isShowing.
Under Swing it works fine. In AjaxSwing 2.4.2 and 2.5.0 the second tab always keeps its content empty.
My current implementation of the new fix is the same as in the sample. See attachment.
The trace output shows that only when I resize the window, I get the showing event and also somehow both textfields are showing.
Though I need a window update on tab change and the isShowing behaviour of Swing.
