Hello,
I found several older threads saying that in order to change process flow due to exceptions I have to either signal the process from my work item handler or pass the error as a result parameter and then check for errors.
I also found information saying that with 5.3 I can now attach error catch events to all tasks, including service and script tasks. But I currently dont see how I can create a signal for those error catch events to handle.
My goal is to visually represent error handling in my process diagram, to distinguish it from the normal decision flow. Currently I am passing back error messages as result paramters and then check in a XOR node, wether an error occured. However since the same nodes are used for business decisions this is undesirable and I am looking for an alternative.
best wishes
Shizanu

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

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.
