srbac cannot validate action with parameter

I have set an action that has a parameter(e.g actionIndex($p)) to alwaysallowed in srbac system. And it’s saved in allowed.php in srbac system. When I try to access the page, I’ve got this message :

Error:403 ‘You are not authorized for this action’

Error while trying to access /page/index.

When I try to remove the parameter inside the allowed.php file.It works, I can access those action. What happen actually? is that a bug? or something that I miss???

thanks in advance…

P.S: I’ve already delete actionRules inside my controller, and I still found those message.
