TypeError: _1 is undefined error

[mduduzik]

I cannot figure out why I get this error when DSCallback() is about to be called. Please help - see my setup and error log below.

Thanks.


Environment:

1. the SmartGWT or SmartClient version and browser version(s) involved;
SmartGWT Pro 2.3 and FireFox 3.6

2. for a server-side problem, the complete logs generated during processing of the request;

3. for a client-side problem, the contents of the Developer Console (see FAQ for usage);

================

4. if there is a JavaScript error, the stack trace logged in the Developer Console (from Internet Explorer if possible); and

5. sample code.

Posts with incomplete information are much more likely to be ignored.

[Isomorphic_Paul]

It's not clear what would cause this error from the stack trace you've posted.

Can you show us your sample code?
If you can simplify this down to a standalone test case that we can run on our end and give us the complete source / steps to reproduce we can determine whether this is a SmartGWT bug or simply a misunderstanding / usage issue.

Thanks
