Anderson, Could you describe what behavior you are getting when you put a collection in the CollectionExpressions? I've used a process variable object like FactObject with a List (lets say a List<SubFacts> subFct ) on it.  I pass in the FactObject, and make it a named variable in my workflow factObj, and put  CollectionExpression => factObj.subFct variable => currentSubFact, I can use that variable within my ForEach loop no problem.  My setup is to pass that variable into a subflow, but I don't think that is important. I may be missing something, is you case different somehow? Bill Hi All To use a ForEach element i need to access a collection inside my FactObject.  (FactObject.list) I tried to call FactObject.list inside a CollectionExpressions but this fail. (Just ok with list defined as a process variable) *So i do something thats a consider a workaround:* 1- I Create a '"Action Node" before a "ForEach Node" 2-In the "Action Node", i get the FactObject and populate the process variable that represents FactObject.list : *FactObject factObject = (FactObject)drools.getKnowledgeRuntime().getObjects(new ClassObjectFilter(FactObject.class)).iterator().next(); context.setVariable("list", factObject.getDefeitos());* 3- And on the "Foreach node" i just  passed the "list" in the CollectionExpressions This is the correct way to do this? Has a better way to get FactObject.list to use on "For Each Node"? On Eclipse, the CollectionExpression of forEach don't have a window (Like Action Editor) to put a MVEL/Java expressions. I think this is a interesting resource.
