The beans are actually available as attributes of the WebContext (which, in the
context of a Portlet is actually an instance of
org.apache.tapestry.portlet.PortletWebContext). So I've figured out how to get
what I want, now I'm looking to automate it.
This works, but is a bit cumbersome:
<snippet file="View.java" status="success">
@InjectObject("infrastructure:context")
public abstract WebContext getWebContext();
public RoleModule getRoleModule() {
return (RoleModule)getWebContext().getAttribute("RoleModule");
}
</snippet>
And this fails:
<snippet file="View.java" status="fail">
@InjectObject("infrastructure:context.getAttribute(\"RoleModule\")")
public abstract RoleModule getRoleModule();
</snippet>
While I'm not surprised by the failing example, I do wonder: what are the rules
for the @InjectObject annotation? Can we use OGNL (or ognl-like) expressions
within its parameter? The docs state that the value is a "HiveMind object
reference". So, rephrasing the question:
How do I bind the results of something like the ognl expression:
"infrastructure:context.getAttribute('RoleModule')" to an HiveMind object?
What's the hivemodule.xml incantation?
Thanks,
Ezra Epstein

I'm not entirely clear exactly what this code is doing, but is sounds like
Tapestry's ASOs (application state objects) are what you want.
They are container-managed objects scoped to either the app or the user session.

If that doesn't do the trick, perhaps you can describe exactly what this JSF
code does....
Cheers, P
