User Register Node Cannot Be Erased

http://drupal.org/node/73179

I almost posted a new issue, glad i looked a little farther down down the queue :)

On the Auto assign role settings page in the Assign from Path section, once you set User Register Node you cannot later remove it, rather, when you remove the contents of this field and save the form, next time you look, your previous entry is still there. I had to go into the database and remove the value for the autoassignrole table node_user_register row to remove it from showing on the form and actually affecting /user/register -- once i removed the value, the regular registration page began working as expected once again.

Confirmed bug also exists in 2.0-beta1.

Attached is patch which will clear a previously entered User Register Node.

I could not erase the "User Register Node:" for a especific role. what I did was create a new role and move my users to this new role.

This has been committed now
