Ive noticed alot of the tips and answers I find here have me subclass
classes that are in internal packages. So a few questions on that. Are
they internal for a reason? and if they are meant to be subclassed, why are
they not in public packages? I was told (or read, or somthing) that we are
not to subclass internal classes, so when told to do so, is it just a hack?
Thanks, Im just trying to understand how to do a few things.

I can confirm that in general, "internal" means "not to be used (much le=
ss subclassed) by extenders of WTP".
But, there is a part of that statement that is implicit: "do not use if =
you want compatibility with future versions".
I'm not sure of the specific "tips" you got, but I suspect they were com=
menting on the "only known current way"
to accomplish something.
As WTP evolves, we will be creating (and evolving) more API ... so enhan=
cement requests in bugzilla,
of the form "in order to do X, I had to use internal classes Y" would be=
helpful to us as we assess priorities.
Of course, the implications for you, is that if you use internals, you a=
re "signing up" for the risk that
you will have to change it in each release to "fix" what ever internal c=
hanges have been made.
This is not something we desire, but many clients do not mind this form =
of "participation"
in WTP -- since I guess the alternative is to sign up for more
participation to do the work to make an API :)
