SYMPTOMS
You use the PossibleValues property to programmatically populate a ListBox or ComboBox control, and the form definition is subsequently stored with the item.

RESOLUTION
Use one of the following methods to work around the problem:


 * Use the AddItem or List method to programmatically populate a ListBox or ComboBox control. These methods do not dirty the form definition and result in a one-off form.
 * Programmatically reset the Message Class field of the item so that it will continue to use the published form and not the embedded form definition. Note that this approach will still result in items having a large size (in bytes).

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
