Hi!

I'm getting a JavaScript error when I try to refresh the data from my GridPanel.

1 - My GridPanel is reconfigured in page_load and gridPanel.OnReadData event, following the example http://examples2.ext.net/#/GridPanel/ColumnModel/Reconfigure/

2 - The error is: Runtime Error in Microsoft JScript: 'I' is not defined.
3815

3 - I made a little test example. The error occurs both when click in button 'GridPanel Reload' of TOP toolbar and when I click on the button 'refresh' of toolbarPaging

Javascript error is already fixed in SVN

You have to replace 'me' by 'this' in 'onClear' method in the following file
Ext.Net\Build\Ext.Net\extnet\src\toolbar\Paging.js

and rebuild javascript files (Ext.Net\Build\Ext.Net\extnet\build.bat) and rebuild assemblies
