Eclipse crashes with GWT designer and other queries

[gurmeet]

Hi,

I am new to GWT and want to use GWT to build my website. I am trying to create few UI pages in GWT. I am using UIbinder to create pages which I think is the only choice to build UI pages (presentation part). Is there anything else?

My queries are as below

1. Eclipses is consistantly crashing a lot when I try to play with ui.xml by deleting the widgets or panels. am I missing anything?
2. When I try to drag flextable over vertical panel and then some widgets, all widgets are stick to top left. i cant resize them. I cant move them. Why is it so?
3. How to debug GWT with TomCat as Google App Engine looks very slow.

Cheers
Gurmeet

1. Eclipses is consistantly crashing a lot when I try to play with ui.xml by deleting the widgets or panels. am I missing anything?

Yes...a test case and associated log files. We can't help without those.

2. When I try to drag flextable over vertical panel and then some widgets, all widgets are stick to top left. i cant resize them. I cant move them. Why is it so?

No idea. Again, we need to see a test case to see what you are actually doing.

xmlns:g="urn:import:com.google.gwt.user.client.ui">
