user control loading JS error - Microsoft JScript runtime error: Unable to get value of the property 'length': object is null or
Hi,
Im having trouble loading user control pages to container page. While loading the container page, a runtime JS error appears saying - "Microsoft JScript runtime error: Unable to get value of the property 'length': object is null or undefined".
It should be noted that my user control pages have GridPanel, Comboboxes, related stores and javascripts in them. I tried to debug and found that if I remove the CheckboxSelectionModel from user controls grid, the user control loads fine in container page. I have used the similer concept with ext version 1.3, but finding there is something changed in implementation of user controls with version 2.0. Any idea what that is?
Thank you
