--------------------------------------------------------------
I think this is a bug in some JRE's, not in the code. An anonymous class should
have access to an enclosing class' inherited protected methods -
onComponentChanged() and onComponentChanging() in this case - but obviously the
JRE things differently.
A solution/workaround is to declare
@Override
protected void onModelChanged() {
super.onModelChanged();
}
@Override
protected void onModelChanging() {
super.onModelChanging();
}
in AjaxEditableLabel and all should be fine. At least it works for me on Mac
10.5.1 with Java 1.5.0.
