Exception when closing grid with filter editor.

[bschrameck]

SmartGWT v8.2p_2012-10-09/LGPL Development Only (built 2012-10-09)
IE9 dev mode

I have a grid with a filter editor. Everything is inside of a tab. Everything works as normal usually, and I can close/destroy the tab without an issue. When I type into the filter editor and then try to close the tab I get the following error:

16:50:53.760 [ERROR] [composer] 16:50:53.753:MDN4:WARN:Log:Error:

This seems to be completely random. Some grids work perfectly fine, others do not.

Any suggestions?

Thanks,

I've dug through the SmartGWT JS code a little bit (ISC_Forms.js). It seems that there are a bunch of references to a form that keeps returning null for the filter editor.

I was able to get this running by checking for null directly in the JavaScript code. I've attached a diff file for you to take a look in case it helps.

We've rolled these changes into the framework. They will show up in nightly builds going forward (8.2p and 8.3d branches)
