You could try to explain a bit more how the User class and the isUserMatching method look like.<br><br>Leo.<br><br><br><div class="gmail_quote">On Fri, Sep 10, 2010 at 11:30 PM, lnguyen <span dir="ltr"><<a href="mailto:mzspdrcr@gmail.com">mzspdrcr@gmail.com</a>></span> wrote:<br>

I'm having difficulty writing this rule.<br>
<br>
Background information:<br>
A User can have a supervisor but it's not required.<br>
<br>
When viewing User information I want to verify that the logged in user is<br>
either the current user or the currentUser's supervisor but I throw an<br>
exception when the supervisor object is null on the currentUser.<br>
<br>
The target is the User being viewed and I have a global object that is the<br>
current user. How can I check to see if the supervisor exists before<br>
evaluating if the currentUser and the supervisor are equal?<br>
<br>
rule 'CanViewUserData'<br>
dialect 'mvel'<br>
when<br>
$user : User()<br>
$supervisor : User( ) from $user.userProfile.supervisor<br>
$check: PermissionCheck(target == $user, action == "viewUserData")<br>
eval(isUserMatching($user)) || eval (isUserMatching($supervisor))<br>
then<br>
System.out.println("The currentUser CanViewUserData");<br>
$check.grant();<br>
end<br>
