[rules-users] Unable to modify collection fields in Guvnor Test Scenarios

I have imported a POJO model jar in Guvnor. The jar is made up of typical data transfer objects, with properties accessible through getters and/or setters. Some of those properties are collections, only accessible through getters, and therefore, they can only be modified through the usual collection methods: add, remove, and so on. Then I have created some business rules using facts from the imported model. What I haven't found is a way to set up such collection fields in the Given section of a Test Scenario. Trying to assign a literal value gives the error: "Unable to run the scenario. [Error: could not access/write property …]" Does anyone know any way to achieve that goal? Bear in mind that I don't have access to the POJO model source code. Thanks in advance. -- View this message in context: http://drools.46999.n3.nabble.com/Unable-to-modify-collection-fields-in-G...
