Hi vishnube8183,

please see this thread on IE11 + SmartGWT 4.1p.

Best regards
Blama

[vishnube8183]

Thanks Blama. This issue is happening on all the versions of IE. We have tested the same in IE 9 , the issue exists and fails with same error.

This looks like an error coming from inside GWT code, not SmartGWT. SmartGWT is simply calling toString() on some object you've placed inside of a Record, and GWT code for that object's toString() implementation crashes.

You may be having the same issue this user is experiencing, where it appears that GWT Proxies are broken in GWT 2.7 and will crash if certain methods are called on them. Downgrading to GWT 2.6.1 fixed the issue for that user.

Thanks for the response.

We have done most of the testing with GWT 2.7 and everything else works fine . We are currently facing issues only with the Inline Editing of the ListGrid. So we may not be able to downgrade to 2.6.1

We were able to reproduce the issue only when we have the List<MenuButton> as one of the ListGrid fields. Is GWT failing on toString method of MenuButton ?

We don't know; the stack trace is not conclusive and we don't have your code.
