[Seaside] overriding RRHandlerEditor for RSS

I want to create a new configuration dialog for my RSS component. I've
already created the proper class deriving from RRComponent and that is
working well. I want to override the RRHandlerEditor as well. It is not
calling my component and I am not sure why or how to debug.
What I did: I already have a class MyRssComponent (derived from
RRComponent) which properly implements isFeed and canBeRoot on the class
side. I added two classes, one called MyRssHandlerEditor (deriving from
RRHandlerEditor) and MyRssHandler (deriving from WAEntryPoint). Inside of
MyRssHandler I override only configurationComponent and change it to
instantiate an instance of MyRssHandlerEditor:
Then, inside of MyRssHandlerEditor I override renderFormOn: so that it is
changed slightly from . I also override registerAsApplication as a class
method inside of MyRssComponent that looks like this:
register: ((MyRssHandler named: aString)
I never see the editor I've defined get called. I've been browsing around
the source for a while and am not sure how to troubleshoot this. If I call
self halt. within registerAsApplication nothing happens, neither with a ' 1
/ 0. '
I do notice that if I put a 'self halt' into the registerAsApplication that
the icon in the squeak browser changes from a green down arrow to a red
flag. I assume this means something. I've noticed that the
registerAsApplication within RRComponent is a double-headed green arrow.
Can someone point out where I can understand what these mean? I've been
looking over the squeak documentation and not sure where to start looking.
