Loading Initial Value in R12 OA personalization using SQL...

Greetings.

In our good ol' 11.5 instance of Oracle, I could create a personalization for a form that would load an Initial Value by calling a function.  The code looked something like this:  =Select xxap_get_payment_batch_name(:PARAMETER.ORG_ID) from dual.

In our shiny new R12 instance, that doesn't seem to work.  Does anyone know if it's possible to load an Initial Value using SQL or a function?  I checked in the OA Personalization Framework and OA Extensibility Framework Guide, but didn't find anything on this topic.

Thanks!
