Description: After refresh the library, the link groups key are changed in cube builder[1101] Build number: 2.2.1.v20070802-0630 Steps to reproduce: 1, New a cube in library, the cube has a joint key between dimension table and facttable 2, Using the cube in a report design 3, Check the joint status in link group 4, Refresh the library in outline 5, Recheck the joint staus in link group Expected result: After step5, the joint status are correct and as same as the status in library Actual result: The dimension table is missing and the joint key is disconnected
