I recently starts to use GWT (1.5) and GXT(1.2.4), and now I'm in a trouble.
In my entry pount, I have a ContentPanel (Gxt) whixh I use to change some frames to show. And the problem occurs when I change the frame to one that have a GridPanel (Gwt-ext) with dates. I try to find a solution, and the most common solution is to use a renderer to get date format. But the problem is if I use the renderer, the page crush. And now I don't know what to do.
