MultiValueControl with list of valid users is not working

Hi, we are trying to do something like this: ``` <FIELD name="ProjectMembers" refname="Custom.Sprint.ProjectMembers" type="String"> <SUGGESTEDVALUES expanditems="true" filteritems="excludegroups"> <LISTITEM value="[project]\Developers" /> <LISTITEM value="[project]\Testers" /> </SUGGESTEDVALUESVALUES> <ALLOWEXISTINGVALUE /> <VALIDUSER /> </FIELD> ``` This works when importing the WorkItem definition file, but fails when trying to create a workitem of that type in VisualStudio (in a pop-up dialog): `ProjectMembers does not have any values to list in the multiple values control. See ...` Changing it to ``` <FIELD name="ProjectMembers" refname="Custom.Sprint.ProjectMembers" type="String"> <SUGGESTEDVALUES expanditems="true" filteritems="excludegroups"> <LISTITEM value="[[project]\Developers]]" /> <LISTITEM value="[[project]\Testers]]" /> </SUGGESTEDVALUESVALUES> <ALLOWEXISTINGVALUE /> <VALIDUSER /> </FIELD> ``` causes the import to fail with: ```TF26171: User/group '[[project\Developers]' is not found. TF26204: The account you entered is not recognized.``` How can we show a list of users from a predefined group in the MultiValueControl? Thanks for your help. **EDIT** using a GLOBALLIST does not solve the issue, because it is impossible to a) reference a 'project' group from a globallist b) to use the `[ ]` syntax in globallist definition
