Active Rigid Bodies and getAttr -t

Having trouble using getAttr to grab an attribute at previous frame for an active body.

For example, if a new attribute p1 has an expression:

Code:
pCube1.p1 = `getAttr -t (frame-1) pCube1.translateX`;


this works fine whilst the body is passive, but when it's active, translateX returns the current X position, not the previous frame's.

I can sort of understand why it fails. getAttr would somehow have to access a previous state in the solver.

But a workaround?

(btw, an active rigid body doesn't have a predefined velocity attribute does it?)
