Yes I have double checked everything and also a collegue looked at this and saw nothing strange.
The urlencode plugin required no configuration, the return value is string and the class url requires a string. And if it would be a type error I would expect the architect to throw an error.
Hi Arnold, this is most likely a bug in the Architect. If you could you create an SR with the exact model number and revision where this issue occurred, we can investigate and fix this.
Is this by any chance a process on an N_Contact virtual page? Seeing trigger.record.name_fx and the duplication of the error makes me suspect it is. If so, if it is an issue similar to what I suspect, then as a temporary fix, you could probably define the process separately on the N_Organization and N_Person virtual pages, or wrap the whole process it in a process component.
