> {noformat}
> The reason is when update the CubeDesc,first update the DataModel and trigger
> clean cache.the DataModel is new doesn't contains lookup tables,
> then update the CubeDesc.
> Before update CubeDesc, all the CubeDesc's cache in CubeDescManager will
> reload and the test cube's DimensionDesc check the attribute "join" and
> "derived" is not match.
> I try to delete the check and add the attribute "join" null check.It works!
> Please review the patch and discuss the issue and patch.
