How do we control the sequence of fields on the List Layout - the default display for a Dynamic App?  I have worked on a DA called Requirements Tracker (I have actually modified John Filicetti's DA that I downloaded from the Solutions Library).  I defined the following fields in sequence:
     Requirement ID
     Priority
     Type
     Requirement
     Description
     Requested By
     ...

The Wizard, for some unknown reason, has decided that, of these fields, "Requested By" is to be the key for this DA.  "Requested By" is the first field in the List Layout and is the forced field for any View that is defined for this DA.  How do I change this?  "Requirement" or even "Requirement ID" would be far better candidates for the key.

The problem is not with individual pick list values in a field.  It is with the way Daptiv selects which field is considered the "key" to the DA itself.  If I want to be sure which field is considered the "key" (the one that is assumed whenever a view is defined and is the first field displayed for the DA under a Project), how do I do that?
