Here is the thing. I'm trying to test a self-defined service task. I have referred to the Chapter 13 in the user guide, and also the "JBPM5 Example - Human Task Forms with Variables - WorkItems" example. They worked fine.
But I met problem when I tried to add an integer parameter in the task. Here are the things I have done:
1. Defined a process with 4 String variables, and 1 Integer varible. Say aStr, bStr, cStr, dStr, and aInt.
2. Defined a process form which is taking 4 String params. And aStr takes an integer value.
3. Put a script task right after the start point. Parse aStr to aInt.
4. Create a MyWorkDefinitions.wid file with the definition of my service task. 3 StringDataType, and 1 IntegerDataType parameters. Packs imported.
5. Create a drools.rulebase.conf with MyWorkDefinitions.wid and WorkDefinitions.conf defined. (Here in the user guide there is a mistake).
Until here, all things went fine. I can see the service task in a new editor window, and can see the parameters when I put one in the canvas. But the problem happened when I assign the variables to the parameters for the Integer one.
I used format #{bStr} for the three String ones, they got accepted. But when I assigned #{aInt} to the Integer param, I got an error window.
Here is a full message in the error log: (+mxtInt+ is the actual variable name in my local file)

I'm new to both JBPM or Drools. I'm not sure whether I'm using this right. Please help me out here.
Also I would like to know if there are any examples with output back to the process.
Thanks in advace.

In *3.5. 10-Minute Tutorial: Using the jBPM Console* I can follow along with the screencast, except when I try to open a Report Template. I either get an error dialog or an empty Report configuration dropdown.
