Jaymer wroteanswer to your question is "no idea".
but, its interesting, cause a few months ago I wanted a way to have a picklist show up with all the options checked - the user would only deselect a few as normal operation. wish there was an option for a "default" status of the PICK ONE OR MORE checkboxes.
This doesn't help Jon's problem, but if you have a pm attribute and you did
FIND ReferenceObjects
CREATE BO
INSERT ReferenceObjects IN BO.pm
Or
FIND ReferenceObjects
CREATE BO
CREATE ChildBO WITH ChildBO.ob_BO=BO, ChildBO.OtherReferences...
That would give you a BO with the elements selected, bearing in mind that the checkboxes being selected means that there is a relationship in place (i.e. the referenced BOs must be created to be checked)
You would need to then have a routine to delete all of these BOs in the event the the user does not proceed to save them
Sorry JonP for highjacking your post.
