Persistence of UserTasks

[mpriess]

Hi,

I have a process with a UserTask and exclusive gateway and I save the values form the form with the following code snippt:

{code}
    public void confirmUserTask(String taskId, Map<String, String> parameterMap)
    {
        synchronized (USER_TASK_ACCESS_SEMAPHOR)
        {
            taskService.setVariables(taskId, parameterMap);
        }
        taskService.complete(taskId);
    }
{code}

After the value is persisted I looked into the database and my value is "serializable".

Now the exlusive gateway use internally an evaluation and return all time false for this expression.

My expression:
{code}
${USER_QA_NECESSARY == 'true'}
{code}

Is this the right way to persist values and use expressions?

Cheers,

Michael

btw. I'm using Activiti 5.12 and JDK 1.7

That depends which variables you provide as part of the parameterMap.
It's a correct way to add variables to the process context. If the values are stored as text, long or serializable depends on the value type.

Ok in my case the map contain only Strings which type is used in the database? My problem is that ${USER_QA_NECESSARY == 'true'} is always false. Which class resolve the value of USER_QA_NECESSARY from the database?

So you are not using a boolean for true but a String value? If it's a String value it will be stored as a String as well. Can you include the exact XML definition you have? I would like to see a bit more than just the expression.

I found the failure. The value was of type String[] now everything works fine for me also the use of boolean expressions
