ListGridRecord can not be cast to TreeNode

Hi all,

I've updated the version of smartgwt from 3.1 to 4.1 and now I have a class cast exception when I drop a record from a ListGrid to a TreeGrid. In the 3.1 version this works perfectly but now i have this problem.

I think this is a regression in the code.

In order to help you, I identify that the error occurs in the class com.smartgwt.client.util.ConvertTo at the line 7037 (com.smartgwt.client.widgets.tree.TreeNode obj = (com.smartgwt.client.widgets.tree.TreeNode) RefDataClass.getRef(components[i]);)

I also saw that in version 3.1 you didn't cast the object.

Can anyone help me.

Thanks
