Database forms stored in 6i, converting to 10g forms (form only has property classes / record group

Hi,

    I'm having an issue with 10g forms and was wondering if there was a workaround to this issue.

    I've got a 6i client/server form that specifically has property classes and record group attributes only on the form (no objects or canvases).   These are attributes common to text items, poplists, etc.... .  Then, we have other forms that we subclass the attributes from this form that is saved on the database.  So basically, we subclass the attributes in some items on a block by clicking the subclass property on the block item.   We are using an 8i database when this option worked.
