couldn't deserialize object

[nicos109]

Hello,

I've tried a very basic example of serializable variable in jbpm and it throws :
Error getting variable map: An exception of type "org.jbpm.JbpmException" was thrown. The message is: couldn't deserialize object

This action is triggered on "task-start" event

package com.action.creation;

import java.util.Vector;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

public class BasicAction implements ActionHandler {

 private static final long serialVersionUID = 9087034555867614310L;

 public void execute(ExecutionContext executionContext) throws Exception {
 Vector myVector = new Vector();
 myVector.add("elem1");
 myVector.add("elem2");
 executionContext.getContextInstance().createVariable("myVector",myVector);
 }
}

Then I try to use the variable in the xhtml file for this task :

<c:forEach var="elem" items="#{var['myVector']}" >
 <h:outputText value="$elem"/>
</c:forEach>

When I try to get the variable from the action class, it works. So the exception is thrown by the forEach tag.

Any ideas ?

Thanks,
Nicolas.

Sorry, this example worked.
But as soon as the class of the variable is my own, it throws the exception, although the class implements Serializable ans has a generated serial serialVersionUID.
