Membership rule for auto role assignment is not getting evaluated on create event with Custom Post-P

Create a simple custom postprocess event handler that populates a isAD field. The isAD field then drives a membership rule into an OIM Role called "ADPresent" if the isAD==1. This membership rule works fine when there is no custom event handler deployed. After deploying the Custom postprocess event handler, the autogroup membership rule is not evaluated. The only way they can get the rule to evaluate is if they manually do an update on the User in OIM. Its happening on 11gR2Ps3.

But the strange is with same setup rule evaluation working properly on 11gR2PS1.
