Error using exportClientData() in release 2.3

Smart GWT Technical Q&A
1

I just upgraded to the 2.3 Pro release and am trying out some of the great new features. Keep up the good work!

I have a ListGrid on which I call exportData(req) which continues to work as before, but changing it to exportClientData(req) gets me the following error.

This appears to be because of mixed versions in your browser cache. That (internal) API does not exist anymore, at all.

3

I’ve tried clearing the cache (Firefox) and trying another browser I don’t normally use (Safari), after clearing the cache on that one too. I’ve also tried “cleaning” the project in Eclipse and rebuilding. ?

Maybe try the trick of switching JDK and switch back (that worked before).

Thanks for the reminder. That did it. The new feature looks great by the way. Users were already asking for an export that includes their custom formula columns and now it’s there. Thanks!
