If you are using ZClasses with default constructors, this is most likely due
to a Product factory method updating a ZClass instance *after* adding it to
a folder. CatalogAware will index the instance in the ZCatalog before it
gets its fields updated in the constructor, which means that what you get
cataloged is a mostly empty object (where 'empty' means 'with default
values'). You should call reindex_object() on the ZClass instance after
changing it in the constructor, and also everytime you change it.

This happens because CatalogAware doesn't track changes to objects. It only
tracks removal, insertion and renaming (I think) which means that when you
cut/copy and then paste the object, the pasted object works as you expected.

    Cheers, Leo.
