I am using GWT Designer for SmartGWT (v2.2), on OS X 10.6.4, 64 bit JVM with Eclipse Helios (and also have a license with active support.)
I've attached a clipped screenshot of the problem I'm having. I am not combining stock GWT widgets, these are all SmartGWT widgets.
The region highlighted in pink represents the borders of placed widgets which are incorrectly displayed (in terms of visibility, and in terms of positioning and sometimes size). I tried to capture the relevant layout hierarchy in the shot. The line shows where the widgets should be positioned - in the upper left corner of the tab area. The actual running program correctly positions and sizes the widgets based on the layout containers.
This is one of a number of examples of layout problems with SmartGWT but I am hoping that there's a common denominator.
Also, compared to my experiments with Ext JS, the editor is *very* sluggish with SmartGWT. Is there a reason for that?
