constrain curve point to null

[clankill3r]

I have a curve with 2 points.
I want one point to constrain the position of null1 and the other point to null2.

I did manage to do this in ICE, but i was wondering if there is a more easy way to do this.
Is there?

The simplest/cleaner non-ICE way is enveloping the curve using the nulls as deformers

Thanks.
I have one working. The other not, and every attempt i do to recreate has the same problem.
When i move, the point moves slower then the null.
See the image.
What am i doing wrong?

Have you tried selecting a point and right click - create cluster with center? With the enveloping check that each point is 100% weighted to each null.

thanks, that works really nice!
