I have found two small issues using the AbsoluteLayout in GXT (or maybe I do not fully understand how to use the designer):
1. Creating a new dialog box. When I add LayoutContainer and set its layout to AbsoluteLayout the designer does not show tool bar buttons (resize, align, etc) for arranging the widgets or form fields.
2. When I add to LayoutContainer (with AbsoluteLayout ) FieldSet and set its layout also to AbsoluteLayout then I can't properly move fields and widgets. I can drag widget to any desired location on the FieldSet but as soon as I release it the widget "jumps" away randomly 10-40 pixels in both directions. The only way I can position and size the widget is to manually modify it's left, top and width properties.
I have the latest WindowBuilder Pro 7.2 (Ubuntu 9.04 64-bit, JDK 1.6.0_16)
