I have following questions:
 (1). DataGrid doesn't show data in TabLayoutPanel

DataGrid creates a HeaderPanel that has three components for header, 
footer, content (see lines 80 to 111 in HeaderPanel.java GWT 2.5). These 
three components are represented by three html "div" as indicated by the 
following screen shot from Firebugs. The content "dive" is initialized to 0 
for its height.




When DataGrid is added into SimpleLayoutPanel, content height is changed 
into 260px as indicated by the following screen shot so DataGrid show data 
as expected. During debug in Eclipse, I can not catch any api call to 
change height.




When DataGrid is added into a ScrollPanel that is added into 
TabLayoutPanel, DataGrid doesn't show data. In Firebugs, I can not see any 
height change, which is still 0. If I change the height in Firebugs, 
DataGrid shows data.

(2). I have a large GWT project,  I can see an icon "Web app launch view 
activator" at lower right corner of Eclipse". This icon is much often 
running to prevent my Eclipse running normally. It displays a few line of 
messages every couple of seconds and gains focus in IDE. It is so 
distracting during debug. Is there some way to get rid of this problem?


I appreciate your help.
