weight paint problem maya2012

Ericoscarj

So with my character im working with blend shapes, and they work without any problems, but when im about to skin and weight paint the skin. But when im about to paint the weight it works fine, but when i go out of weight paint mode and enter it again to continue to paint weights, i get an error that says:
// Error: Expected a skinCluster deformer or a deformed shape. Found 'blendShape1' instead. //


I did reset all the settings and i cleaned everything up with the rig and skeleton and the blendshapes works perfect too.

please help anyone, i have a deadline for this project:<
