Title: Calling a source procedure from a button on a memory form and going to another p
Post by: terryd on May 09, 2014, 01:34:59 AM

Hi Bruce
Following up from the question I asked in the webinar last night.
I have placed the call to the TagTransfer source procedure in the Validate::TagTransferButton Routine Add serverside code here and the procedure gets called correctly.
The serverside code is called 3 times, once when the form generates the button and twice when the button is clicked.
I can live with this but it would be preferable to be able to control when the TagTransfer(p_web) is called.
Secondly I would like to close the form and return to the menu.
In the On Click URL I have entered 'index.htm' which returns me to the menu but doesn't reset the session variable that I would like to reset to 0 i.e. p_web.SSV('StatusID',0). I can't set this in the tagTransfer procedure because of the three calls, the first two of which should not change this variable. Is there a location where I can set this to 0 just before or after the Index.htm operation?

Hi Terry,

>> The serverside code is called 3 times, once when the form generates the button and twice when the button is clicked.

then you've done something wrong. The Validate:: routines only get called when the field is completed.

>> Secondly I would like to close the form and return to the menu.

On the same button? On the same click?

Cheers
Bruce

Yes I had the call to the source procedure in 2 different places.

Yes on the same button, same OnClick

With the On Click url of 'index.htm' the procedure does go to the menu. I would like to set a session value just before the 'index.htm' is called

Terry,

you can't do both.
Probably your best option is to pass a parameter as part of the URL call. Note that the call to index.htm, and the server-side-code can run in either order - you can't predict which one will happen first, because they're running on different threads.

So add a parameter, and do a p_web.StoreValue in the destination procedure.

cheers
