I recently performed a data type conversion from text to pick list. So now my field is of data type pick list. It will be used on task records when the record is dynamically created by python integration. The field is a picklist on the new task record which I can confirm.
However , when I tried to use this field as a parameter to the ISPICKVAL() function inside a Visualforce email template, I got an error:
Q) Why would a newly converted pick list field fail to be used as a parameter inside the ISPICKVAL() function? That does not seem to make any sense. Note: the relatedTo field in the VF email template is set to Task. Thanks
ISPICKVAL
is just not supported in a Visualforce Template. Hard to find a concrete indication of that in the documentation though.
