--------------------------------------------------------------
Hi all,
I'm just getting started with jBPM, and I have a small question about XOR gateways. At the moment, our nodes have two endpoints, and the code for one endpoint looks like this:
switch(result) {
case OK:
return true;
default:
return false;
}
While for the other endpoint (pointing to an 'end event'), it looks like this:
switch(result) {
case OK:
return false;
default:
return true;
}
So in the other constraint it's the other way around. To me, this looks like a bit of duplication, and in this example it's not too bad, but in more complex examples, it's trickier. So I was wondering, isn't there a better way to do this? Isn't it possible to create one piece of code, and let true go to one sequence flow, and false to the other, without having the need to duplicate the code? Is something like this possible??
Thanks for the help,
Kind regards,
Erik

[jBPM] - NodeInstanceLog and Human Tasks relationship

How to get the data about who acted on a task using the NodeInstanceLog Table.
The NodeInstanceLog table will give the entries about a processInstance regarding the nodes that were entered and exited. If, in the process, there is a Human Task node and during the execution of the process the flow reaches at the human task node, an entry is creates in NodeInstanceLog table, task is created etc, then some user acts upon it and completes the task, again another entry is created in the NodeInstanceLog showing the exit information of the node.
But I am not able to find out who has acted upon the task. This information is present in the Task table but there is no relationship between this table and NodeInstanceLog.
How should I relate them?

I have deployed jbpm (drools-guvnora and jbpm console) on Tomcat 6.0.35.
I have created a simple process (Start --> Task Log (default WorkItem) --> End) in guvnor but when I execute this process on console I have this error:
*exception*

[jBPM] - How to use a custom object as process variable

To view the discussion, visit: https://community.jboss.org/message/744959#744959
--------------------------------------------------------------
Hi,
I want to use me.bpm.test.Application as a variable for a process. I'm fully using the web based guvnor designer to design the process.
package me.bpm.test
public class Application
{
public String firstName;
public String lastName;
public Date dateOfBirth;
public String address;
public boolean isApproved = false;
public int getAge()
{
int age;
// some code to calculate age using dateOfBirth
return age;
}
}
1. How do I add this class to Guvnor and/or JBPM Console so that in the runtime console can use the class.
2. How do I define the Mapping (assignment, DataInputSet, DataOutputSet) from freeform templates (.flt) to the process level object? Can I use firstName_out->Application.firstName ?
Thanks in Advanced.
