Your class is broken; you accept PropertyChangeListeners but don't
send PropertyChangeEvents. Jess handles your modify by calling
setName() on your object (your object will actuall be changed) but
then relies on receiving the PropertyChangeEvent to tell Jess to
update working memory. Since that event never arrives, working memory
is never updated.
Your setName() method has to call firePropertyChange(), something
like:
public void setName(String name) {
String oldValue = this.name;
this.name = name;
m_pcs.firePropertyChange("name", old, name);
}
Alternatively, you can simply remove all references to
PropertyChangeEvents. Jess will then be able to modify the object and
working memory will stay in sync, but of course if the object is
changed outside of Jess, Jess won't know about it.
