Good Morning,

I have the same problem

Best Regards

[darkling235]

I've tried to upgrade my system to get around the "Index Contraint" problem but now I have this problem as well. If GXT doesn't work with GWT 2.2 I wish they'd tell us

[micgala]

Hi.
There are lots of posts in this forum telling this.
The last public release of gxt was made prior to gwt 2.2, so, at that time, there was no change of gxt team to tell:
This won't work with gwt 2.2.

But after gwt 2.2 was released, many forum posts were created, and they were all replied :-)
