I am getting the error "ERROR FieldInstantiator : couldn't instantiate type 'org.jbpm.graph.def.ActionHandler' with the default constructor" when i am trying to run the test programe after adding action.
I am using GPD . Eclipse pos a window when i try to add action to the process filesaying there is a error.see the log file. but it did added the code to xml file.
Any idea please ?
It was my mistake that I have selected ActionHandler instead of HelooActionHandler. Now the program works. But Eclipse still showing error window when i update properties of an Action. But it is not a big deal.
