I had the same issue, thanks! Now I'm using beta3..
Another question though: I see that Recorder.initIds() assumes that getPalette().getModelCollection() is never null.. Is this by design? Should I check my "backing bean" for null collections before passing it to the CompoundPropertyModel?
(Or maybe I could override CompoundPropertyModel.AttachedCompoundPropertyModel.getObject() so that it creates the empty collection when needed.. X-) )
Many thanks in advance!

I have also the same problem, because my backend bean collection attributes
sometimes is null. I have some client logic bind to this attribute a I need
that it will be null.
I understand that is not so good when Pallete creates some List impl. But I
thought about it and I see solution in Palette's method for example called:
protected List getDefaultList(). Everyone who need to have bean attribute
null and if also need use this attribute for Palette component can override
this method a return default the List impl, which need.
Can you please think about it? It's my wrong ?
Thanks you very much!

I see.. So I'll let my implementation of CompoundPropertyModel create it as needed.. Thanks for your answer :)

i dont know if it is by design or not. it makes sense to me that you pass in
a model with at least an empty collection, otherwise palette has to create
an instance of some collection which isnt as clean.
