Rational Team Concert work item adding type attributes null UUID error
In Rational Team Concert, web version, we have an existing work item and when trying to modify attribute and associated it with a new enumeration, when we try to save (after making the change) we receive a error at the top of the page: (Red line) with message - X null UUID
Can someone give the steps to modify an existing attribute and associate it with a new enumeration list? or is this even possible? Yes, we do have existing work items and they are related to an existing enumeration list that we no longer want to use.
One answer
changing type of an existing attribute is currently not possible. we have an enhancement on it : Provide the ability to change the attribute type of a work item attribute to a compatible different attribute type (180112)
So alternative would be to add a new attribute with the requited enumeration list as its type and remove the earlier one. Take care of the existing work items by moving old attribute values to the newer one either by
exporting the workitems and importing it back but with a new mapping
or
running a query and manually updating the newer attribute with corresponding values from earlier attribute
here are more discussions around modifying attribute type which you might find useful:
