So, I've got this object:
public class MySerializableClass implements java.io.Serializable {
|
| private static final long serialVersionUID = 1L;
|
| int member;
|
| public MySerializableClass(int member){
| this.member = member;
| }
|
| public boolean equals(Object o) {
| if (! (o instanceof MySerializableClass)) return false;
| return ( member == ((MySerializableClass)o).member );
| }
| }
which I put into the context in a certain node by:
context.setVariable("a", new MySerializableClass(4));
and then further down the workflow, I try to retrieve through this operation:
MySerializableClass msc = (MySerializableClass) context.getVariable("a");
And this operation leads to this error:
java.lang.ClassCastException: common.types.MySerializableClass

Now, I've searched the forums, and the best awnser that I've got was this one from
JoeDeveloper:
http://blogs.sourceallies.com/roller/page/joedeveloper?entry=jbpm_3_1_aut...
Now, I've tried his approach and still no go, so what possibly could be wrong here?
PS: My class is taken from the jbpm examples (VariableInstanceDbTest.java), which doesnt
try to get the object back, only does an assertEquals.
