I'm sure that would work fine. I actually created a quick fix method which does
just that (as you can see below), and it did validate correctly. The method
returns true if validation passes, and I then only call taskInstance.end();
Doing it this way for now, I am then able to get around the "end" bug aswell.
I've pasted the method below which may help people with a workaround for now.
/**
| * A bug workaround method to validate that all required
| * variables in a task instance have been set.
| * @see Bug[2] at the bottom of this class.
| * @param taskInstance
| * @return boolean true if validation passes.
| */
| private boolean validateTaskInstanceVariables (TaskInstance
taskInstance) {
| boolean pass = true;
| TaskController taskController =
taskInstance.getTask().getTaskController();
| if (taskController != null) {
| List variableAccesses =
taskController.getVariableAccesses();
| if (variableAccesses != null) {
| String missingTaskVariables = null;
| Iterator it = variableAccesses.iterator();
| while (it.hasNext()) {
| VariableAccess variableAccess = (VariableAccess) it.next();
| String mappedName = variableAccess.getMappedName();
| //first check if the required variableInstances are present
| if ((variableAccess.isRequired())
| && (!taskInstance.hasVariableLocally(mappedName)
| || taskInstance.getVariable(mappedName)
== null)
| ) {
| if (missingTaskVariables==null) {
| missingTaskVariables = mappedName;
| }
| else {
| missingTaskVariables += ", "+mappedName;
| }
| }
| }
| // if there are missing, required parameters, set pass to false.
| if (missingTaskVariables != null) {
| log.debug("Missing task variables:
"+missingTaskVariables);
| pass = false;
| }
| }
| }
| return pass;
| }
I can try and apply the patch on my system to test if validation works, but I
am not building from source so would take me some time to setup my environment
and get to it.
