objectname.Submit(string urlName, ref string response, DWControl dwObject{, boolean format})

I was under the impression that syntax 1 would send all the necessary buffers from the dwObject...including the 
delete buffer. But all my tests of deleting a row from a grid dw with multiple lines were having no affect, but not 
returning any errors.  After many, many tests, I finally switched to syntax 3, where you explicitly indicate which buffers 
to include, and then it worked fine.  The tutorials I reviewed indicated that all buffers are sent with syntax 1. 
The PowerBuilder help for this method doesn't state one way or the other...it just shows the different syntaxes and a 
few examples.

Is syntax 1 supposed to include all buffers?  Was I doing something wrong?

Note that i used the implicit default "format" of TRUE, and explicitly set format to TRUE, but no difference.

Thanks,
Glenn
