For multiple selections, InfoPath actually inserts a new instance of a repeating field when you select (and removes it when you deselect). My guess would be that it can't do that with a secondary data source....https://www.infopathdev.com:443/forums/thread/125405.aspxFri, 24 Nov 2023 07:51:24 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:125405matts0https://www.infopathdev.com:443/forums/thread/125405.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=125405Hi, I have added a "multiple selection list box" control to my form and bound it to an element in a secondary data source (local XML). For some reason, when previewing the form, I am not able to change the state of the checkboxes. Is this a limitation with secondary data sources? Text box controls bound to elements in the secondary data source can be used without problems. Any advice appreciated! Thanks, Matts
