I'm pretty sure now it is a multiple different classes /classloader issue as mentioned above. I extended the VariableInstanceDbTest with the following test: | public void testJSFSelectItem() { | Collection selectItems=new ArrayList(); | selectItems.add(new SelectItem("BLA","Fasel")); | selectItems.add(new SelectItem("BLoe","Fasel2")); | contextInstance.createVariable("selectit1",selectItems); | processInstance = saveAndReload(processInstance); | contextInstance = processInstance.getContextInstance(); | ArrayList selectItemsRead = (ArrayList) contextInstance.getVariable("selectit1"); | assertTrue(selectItemsRead.get(0) instanceof SelectItem); | } | and the test works. So try removing the jsf libs from your war/ear and only use those on the classpath. So to me it is now (until proven otherwise Karsten... ;-)) not a jBPM issue anymore View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4083853#...
