Hi,
I am getting classcastException while calling the action handler in the
transition like this.
|
| <transition name="Check Duplicatelist" to="Check Duplicatelist">
| <action class = "com.sample.action.AutomatedAsyncflowHandler">
| <message>CheckDuplicatelist</message>
| </action>
| </transition>
|
|
my action handler is
| package com.sample.action;
|
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
| public class AutomatedAsyncflowHandler implements ActionHandler {
|
| private static final long serialVersionUID = 1L;
|
| /**
| * The message member gets its value from the configuration in the
| * processdefinition. The value is injected directly by the engine.
| */
| String message;
|
| /**
| * A message process variable is assigned the value of the message
| * member. The process variable is created if it doesn't exist yet.
| */
| public void execute(ExecutionContext context) throws Exception {
| context.getContextInstance().setVariable("message", message);
|
| System.out.println("i am in the MessageActionHandler" +
message);
| }
|
|
| }
|
|
this exception is coming for me
