Hi, When I have a task with more than one group assigned and I want to get the potencial owners by one groupId, instead to get the ones filtered by the given groupId, I get all the tasks. I found a property to available that filtering which is "disable.all.groups", but after setting it and continue not working, I took a look inside the code, and I found in UserGroupCallbackManager / public String getProperty(String name) { if (this.callbackproperties != null) { this.callbackproperties.getProperty(name); } return null; } / It's always returning null, I'm using drools version 5.4.0.Final and jbpm version 5.3.0.Final. I can't find a better solution that you can change it in the code :S Thanks in advance, Erica -- View this message in context: http://drools.46999.n3.nabble.com/UserGroupCallbackManager-getProperty-do...
