Hi Dan!
Thank you very much again. It seems if you can make
it to the point where you can 'Edit' an instance, the necessary services are
injected
and you will get a drop down list.
The injections 'setDomainObjectContainer' and 'setToDoItems' etc.
are called when you edit an existing object but not when you try to allocate a
new one.
That would mean, only if you make a property @Optional the choiceProperty()
method will
be called (but only when editing the instance afterwards).
Maybe I'm completely on the wrong track here...?
Anyway, thanks to your suggestion it now works as expected with the
autoComplete annotation, so my problem
is solved in a way. :-)
So long
Christian

Subject: Re: problem with choices for properties
Hi Christian,
Just coming back to you on this...
I added a new property to the quickstart archetype's ToDoItem [1], and it
seems to be working ok [2], [3], [4].
The only thing that might be a bit odd is the rendering of "(null)" when no
reference is set... perhaps that should simply be blank. Otherwise, seems
ok...
Dan
