Thanks, Matt. Now I got it, but // we can't // reference the WatcherSetupUtil class in the component, because the // WatcherSetupUtil can't be generated until after the component class is // done compiling.
Can you ask Paul why he didn't use reflections to reference WatcherSetupUtil??? It looks much more reliable then generated code approach. - Max --- In [email protected], "Matt Chotin" <[EMAIL PROTECTED]> wrote: > > From Paul (who wrote the binding support in 2.0) > > > > For now, analzying the catalog.xml files seems like it will work fine. > > Alternatively, he could compile an application with the components in it > and then look for the WatcherSetupUtil's in the generated SystemManager > class.
