It is well documented how to save the contents of a multi-select combo box to a Single Line of Text field, but not so how to successfully get the content back into the DefaultSelectedItems of the control. I will do two examples here (both related) – one on a Choice field and the other on a list of items. Items referenced as follows Choice field Items Update of Data Card  DefaultSelectedItems List Field Next is a list based on a field from another List) – I will refer to the elements as follows Items Update of Data Card DefaultSelectedItems and that is about the extent of the process. I hope this is useful to you.
