[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-3154) Better if Context.remove() actually returns what was removed.

[Tobias Hill (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBSEAM-3154?page=all ]

Tobias Hill updated JBSEAM-3154:
--------------------------------

    Description: 
In short: it is quite common to let a remove-method on map-like structures 
return the removed object. I can't see any reason why Context.remove() has 
to return void. 

It would let me write: 
Object bar = getSessionContext().remove("foo");

Instead of:
Object bar = getSessionContext().get("foo");
getSessionContext().remove("foo");

Moreover: This micro-enhancement to the api would make it easier to "remove and show" an object from an EL-expression as well.
