GWT Designer encountered unexpected internal error.
This could be caused by a GWT Designer bug or by a misconfiguration issue, conflict, partial update, etc.
java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
I'm using Indigo up to date and GWT SDK 2.4.0 rc1 and GWT Designer 2.4.0 r37
But tested with Helios and GWT SDK 2.3.0 r36 with same results.
On the other hand there is no problem with <g:header> and when used in runtime mode, works well.
I've attached one report zip from GWT Designer.
Thanks
Daniel
