The function "doforeach" allows me to call a function by string. I use

We are on 7.0.

I'm glad you brought this up Stefan, because I've been looking for such a use case, so I'd like to understand this a little better in order to know where the appropriate enhancement would fall.

How are you determining the value of the text PV that each process should have?

Side note: I'd tweak Owen's example slightly and say:
apply(
if(pv!text="a", rule!a, if(pv!text="b", rule!b, ...)),
{ri!data}
)

If you're at Appian World, I'd be happy to meet with you tomorrow (Wednesday) to discuss in person.

Hi Annelise, in my framework I have a single process model called "ticket" which has two data containers. One is defined as a static CDT PV which contains the basic data each ticket has. To display this data in different fashions this CDT has a field "template" which maps to a HTML template file and is rendered using "textfromtemplate". The other data container is a PV of type text which contains the externalized data of a CDT which content depends on the type of the ticket. To be able to display this data on the single ticket dashboard I use a "display_x" function that internalizes this data and renders it using "textfromtemplate" as well. Now my first CDT has a field of type text that holds exactly the name of this function.

In a ticket type specific setup process that runs just before the ticket process is created all this setup stuff is done. So what I wanted to know is: Is there any other way to call a function by name except of my hack with doforeach?

I hope I was able to explain what I did here :-)
