Today I was starting to run a few simulations of the do-find-matching action in Designer 4.9 and found, the simulation is broken, if muktiple objects are returnd in the query.

As long as the response to the query, buid besed on the do-find-matching-object is containing only one instance, the simulation is working as desigend, but if multiple instace are returned, there is a null pointer exception thorwn in designer.

Demo Driver : Match found: src-dn='b' association='b'

Maybe I am too blind to see, but I cannot see, why there is a null pointer exception - if I only include one <instance> element everything is working as expected.

In this case, I would expect the error.do-find-matching-object variable should be introduced

Kind regards
