How would you recommend implimenting such a combobox.  I am using the SF combobox and populating that combo with a business object.  I have tried adding a row to the business object (Not Selected) and not saving the data and that seems to work but I just can't find the right setting to get the form to NOT prompt to save if there is changes on the combobox's business object.  My form include settings are all set to DeterminedByBusinessObject and this business object is not directly on the form, it is in a custom user control that is being added to the form, no BOTranslation is being done for this BO. Its include settings are all set to false.  When I look at the forms businessobject coolection in the unsavedchagesexist event I notice that that bo is listed and isdirty is set to true.

Any suggestions?
