Expression using Map access not working....

Question

I am attempting to use the ability to access a Map by key from a binding expression on the jsp. I have extended HashMap and overridden the get method in order to return a Boolean from the get(key) method.
This works:
rendered="#{bean.enabledFunctionSecurityMap['key1']}"
it ends up calling the bean.getEnableFunctionSecurityMap().get("key1");
This should work also but doesn't:
rendered="#{bean.enabledFunctionSecurityMap['key1'] or bean.enabledFunctionSecurityMap['key2']}"
Any reason why a single Boolean returned from a Map would work fine, but a more complex statement with 2 Booleans will not work. Doing a statement like this just accessing multiple boolean getter functions on a bean works, how come access muiltiple Map returns does not?
Any help is appreciated.
Thanks,
Mike

Answer 1

All righty then, I solved my own problem.
There were actually 2 issues.
1. I could so far only get this to work if the Overridden Map Object is registered as a manged-bean itself.
2. I was testing to see if it worked by using System.out.println methods in my overridden get() method. Appearantly the JSF EL is smarter than I am. If you have #{binding1 or binding2} and binding1 evaluates to True, binding2 is never evaluated. The expression is short circuited and returns true... DUH....
So this expression fires both bindings....
rendered="#{enabled['key1'] and not enabled['key2']}"
Where enabled is...
<managed-bean>
<managed-bean-name>enabled</managed-bean-name>
<managed-bean-class>security.EnabledFunctionSecurityMap</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
Next step will be to try and figure out how to get this to work where the EnabledFunctionSecurityMap is on another bean.
Hope this helps anyone trying to do the same.
