Identity.instance().hasPermission doesn't work

[m.schmidt]

Hi,

I'm using the default JPA permission store and drools rules to grant admin users all rights.

But i have problems with Identity.instance().hasPermission when a non-admin tries to perform actions.

It returns sometimes 'false' although it should return 'true'.

That's the DB row:

<id,target,action,recipient,discriminator> = <125,'post:54','viewPost,downloadPost','testuser','user'>

This view code always works:

<h:column rendered="#{s:hasPermission(PostViewer.currentPost,'downloadPost')}">

This Java code works:

this.post = sessionData.getPost();
downloadable = Identity.instance().hasPermission(post, "downloadPost");

This Java code doesn't work:

Post p = postDAO.findByID(kc.getPost().getId());
System.out.println("bbbb: " + p.getId()); // prints 'bbbb: 54'
downloadable = Identity.instance().hasPermission(p, "downloadPost");

Am I doing something wrong?
Why does it fail only sometimes?
