Customize work item : found in release & resolved in release not populated

In TFS2010 I am cu开发者_运维知识库stomizing the CMMI template. I want to have 2 value-lists for "Found in build" and "Resolved in build" custom fields.

The suggested values must be taken from the builds that are populated by TFS in a globallist.

How can this be done to get it work ?

In the WorkItemType definition, edit the Found In Build and Resolved In Build fields to have an ALLOWEDVALUES of one of the "Builds" fields in the global list. For example, if you have ProjectA and ProjectB, and you wanted your fields to have those in a dropdown, set the ALLOWEDVALUES to GLOBALLIST: Builds - ProjectA and GLOBALLIST: Builds - ProjectB

That will give you the dropdown list. Be careful, though, as those lists can get huge, and quickly!
