You will probably need to write logic code to perform the same functionality.https://www.infopathdev.com:443/forums/thread/5753.aspxWed, 02 Aug 2006 12:26:57 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:5753quaero0https://www.infopathdev.com:443/forums/thread/5753.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=5753Hi!<br /><br />I've created a XML-schema-based (with unique-, key- and keyref- constraints) form, but infopath don't check it. So it's possible, that I get two objects with the same ID or an empty reference.<br />How could it be? Where is my mistake?<br /><br />Thanks for your help.<br />quaero
