I see what you mean. I do not wrap my calls to getProperty inside
normal looking getters like that so I've not had that issue.
I'm not sure if you're saying you have had a problem naming things
this way or if you're saying you expected there to be a problem - I
don't know if this is an issue or not, but I wouldn't be surprised.
I guess what I am trying to say is that it is too easy to break things
with Tapestry without any warning that it is not allowed. I just try to
get a feeling of how Tapestry works.
I noticed that initialize is never called. Isn't it needed for the
same reason as pages?
The first time when going to a page with this component, it will
enter both getValue and setValue. But the next times it will enter
just setValue.
The value 50 or 40 are actually never displayed on my page. I will
only see the value that was given to the value parameter.
I'm not sure off the top of my head about component parameters like
this, but initialize() is a page thing, not component if I remember
correctly.
So does that mean that instance variables are not allowed for components?
Does anyone else know why the getter and setter are called like this?
I highly recommend you get Howard's book if you don't already have it
- he's provided a lot of helpful state information in there.
Yes I have it and almost finished it. Still I think I could a learn a
lot of it if I read it again now that I have a little bit experience
with it :p
If I could make any recommendation for Tapestry. Make it easier to avoid
having abstract classes. Actually.... don't enhance classes as well. It
is not transparant what is happening and decreases the benefits of
strong typing and fixing errors compile time.
