Actually why not do this?
MyWebObjectName : MyDesiredComponentName {
user = session.user;
}
This is what I thought I wanted to do, thanks.
Can you clarify if this below would be a true and generic version of
what you've suggested for those of us feeling small of brain ;-}
It's a very useful thing to do. If your custom component returns true
(the default) for synchronizesVariablesAndBindings then you just need
public setters/getters for 'user' for example. Otherwise, you can do
away with the setter and do as I suggested before:
public User user() {
if ( _user == null )
_user = ( User )valueForBinding( "user" );
return _user;
}
ie. Can I do this sort of thing generally with WOD?
MyWebObjectName : MyDesiredComponentName {
publicVariableInMyDesiredComponentName = someValueIWishToPass;
}
Yes.
Finally, is there any related Apple or other doco I can read that
deccribes WOD usage generically?
It can be helpful to look through the example custom components:
- /Developer/Examples/JavaWebObjects/Frameworks/
- /Developer/Examples/JavaWebObjects/Source/JavaWOExtensions
- /Developer/Examples/JavaWebObjects/WOExamples
- Project Wonder's ERExtensions
Don't forget to read the javadocs for WOComponent and it's superclasses.
But as for actual instructional/point-by-point documentation. It can
be helpful to go back and look at the legacy docs where they listed
actual programming topics -- who knows why they've not kept them
handy with the new pages :-/ (Yes, I've filed a bug a loong time ago)
Case in point... diminishing returns...
