Subscription Filter on a string list


is there a way to create a filter for a receive steps which checks if a string contains a given element?

I didn’t find anything in the documentation, Advantage or in the forums here.

More details about the problem:

We want to check for elements which are automatically added to a list without a fixes order.

Possible but not elegant so far would be

  • concatenate the field into a string with a delimiter and use filter condition contains.
  • create a document type dontaining fixed element for the possible values, set them before sending and check for their existence in the filter (not very generically though).

For better flexibility (and better programming style) we would prefer populating a dynamic string list, but I found no way so far for filtering on a string list.

Any ideas?
