On the leave request form that I'm working on, there are certain leave types that require that the form originator
attach some sort of documentation, like a doctor's note if they are claiming sick leave.
In my start point, I have the "Permit adding attachments" checkbox selected, and store the attachments in a process variable called "formAttachments", which is of type "document<list>".
In my processing, I need to verify that they attached a file. I have a decision point with a conditional route that is executed if an attachment is found in "formAttachments". I've run into a problem trying to find the proper way to make this determination.
I currrently have the expression:
get-collection-size(/process_data/formAttachments) != 0
I've also tried:
getDocAttribute(/process_data/formAttachments[1],"wsfilename") > ""
to check for the existence of a filename attribute. Neither of these works.
Could someone please help me figure out the proper way to check for the attachment?
Thanks much for any help.

Got it working. Should have used "get-collection-size(/process_data/formAttachments) > 0"

Upon further testing, I found that I had to create an integer variable called "numAttachments" and assign it the value of "get-collection-size(/process_data/formAttachments". I then check against the value of "numAttachments" in my conditional route. I'm assuming that get-collection-size does not evaluate as an integer, so you have to cast it to an integer value before you can use it.
