Callback execution issue for DataSource Vs DynamicForm

[GoogleCodeExporter]

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 of a DataSource.
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) of DynamicForm.
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,
Uditha Perera
