Override transformRequest(), not able to getSort().

We've checked in a fix for this in the SGWT 4.0d codestream. It should be in the next nightly build.

Just tested against:
SmartClient Version: SNAPSHOT_v9.0d_2013-04-24/LGPL Development Only (built 2013-04-24)
and the same exception occurs?

Actually, it can't really be the same stack trace, since one of the functions in the original trace is no longer called, but it may look similar.

We were able to reproduce what we thought was the same issue with one of our internal samples, and fixed that. However, it appears like a bit more is required for your case, so now we've made that adjustment as well. It's been verified with your code that we no longer see the ClassCastException, and now hit a 404 warning from your DataSource (I'm guessing because you didn't include the xml). That addresses your original issue.

Check the next nightly.

Verified as fixed in:
SmartClient Version: SNAPSHOT_v9.0d_2013-04-28/LGPL Development Only (built 2013-04-28)
Thank you.
