Dear all,

I've set up a group and a simple rule, worked.

Then I got curious how much I can do with the expression language. Dug a bit through the linked documentation and then thought I would like to have a filter on all lastnames containing a double-nn (doesnt make sense, but just some understanding as objective).

Switching to expression language and adding one more condition:

user.division == "0123" AND 

user.userType == "0003"

Worked.

Adding a string operation:

user.division == "0123" AND 

user.userType == "0003" AND 

String.stringContains(user.lastname, "nn")

Fails.

So, how to use the String.stringContains properly?

I tried with and without ==, always got "invalid expression". The linked docu states that stringContains returns a boolean, so the == shouldn't be needed. Yet, that doesnt seem to be the case. Am I missing something?

I dont think the "?:" operator will help me there either, or does it?

Kind regards
