The "mat-" prefix cannot be used in ng-material v1 compatibility mode

[mbx2015]

I already updated @angular/material and @angular/cdk to v beta.12 but I got this error
ERROR Error: The "mat-" prefix cannot be used in ng-material v1 compatibility mode. It was used on an "mat-list" element.

What's wrong ??

If you are on beta.12 and have already made the conversion to mat-, then you should be able to remove {provide: MATERIAL_COMPATIBILITY_MODE, useValue: true},

I don't use MATERIAL_COMPATIBILITY_MODE in my code

I'm currently using md2, that's the source of the problem,
thanks
