access denied (error message) using show region behaviour
I'm sorry Jason, I don't quite understand what you are suggesting here.
You say 'Select the region that should show if access is granted, and add a show region behaviour' ... What would this region be? .. How does this apply to a link that is selected? If they have access the link directs them to another page.. If they don't the error message appears.
All links should be visible from this page because the home page will hold information relevant to all blocks/estates. If I apply a show region to each link with its own access rule they will disappear depending on who is logging in. Plus I can't see how I can trigger the error message when a link is clicked.
