Hi,

On IE7 & IE8 I am getting below exception on production mode.I have no problem on IE9, chrome and Firefox.
On window I get this:com.google.gwt.core.client.JavaScriptException: (TypeError): Unable to get value of the property 'nodeType': object is null or undefined description: Unable to get value of the property 'nodeType': object is null or undefined number: -2146823281

I have a tab panel with two tabs.One of the tab has radio buttons, and combo boxes, accordion panel and 5 content panels each of them including a check box tree inside.
I also tried with the GXT3.0.4 version, but I got the same exception.
But there is not a scenario during that I get the exception, I click the radios, select data from comboboxes which set data to check boxes in accordion panel.

Thanks
Ozlem

Can you share a test case that demonstrates this issue, or link to an example that causes an exception when following these same basic steps?

We have the 'standard' bug format to try to get all of these details right away, to ensure that we can reproduce the problem and test it well enough that it cannot come back in a later release.
