Re: GWT call-back BUG

Hi

I could be way off here, but it looks like a SmartGWT framework bug?
You should check the SmartGWT issue list:

Hi All,

One of the GWT Bug(Sorry, as I think It's a Bud) ate my valuable development time recently.

I was saving my 4 DynamicForm's data by using 

addData(Record record, DSCallback callback)  method.

Saving back-end method had a business validation which return RunTimeException with validation error message.

If due to validation, saving get interrupted, i didn't want to run code inside execute(DSResponse response, Object rawData, DSRequest request) 

But the issue was, neglecting there's a RunTime validation exception or not, lines inside "execute" got called which was not supposed to call when RunTime validation exception thrown.

After so many testing, wasting time, I found that the solution as using a DynamicForm object to save data with call-back would work.

That's calling 

saveData(DSCallback callback)  with execute(DSResponse response, Object rawData, DSRequest request) 

If I use this way, when RunTime validation exception thrown when save data, lines inside "execute()" not get called.

So the lesson is, 

DataSource.addData method with call-back will execute lines inside "execute()" method when RunTimeException is returned or not. (In Both time)

DynamicForm.saveData method will call-back will not execute lines inside "execute()" when RunTimeException is returned. call otherwise.

Can you experts elaborate on this. Is this a really GWT issue or is that something GWT developer purposely done.??

Thanks in advance,
