IE7 is killing me - Error: 'undefined' is null or not an object
Having an issue with my code where it works fine in FF but not in IE7. This is running with the debug extjs code. It says in IE7:
Error: 'undefined' is null or not an object
That's referring to the renderer on my dataGrids I think. Problem is that even with adding renderer: 'undef' to all of my columns it still isn't working. Maybe it's something else. Can someone help? It might be something other than dataGrids but I'm not sure.
Also, I have searched the forums and this error may sound like the others yet it is not solved by the same solutions. It's also not JSON related because there's no JSON involved on this page.
