Subject [jira] Created: (BEEHIVE-608) Overriding Controls annotated member in the inheriting page flow cause exception
Date Thu, 05 May 2005 21:16:07 GMT
Overriding Controls annotated member in the inheriting page flow cause exception
--------------------------------------------------------------------------------

         Key: BEEHIVE-608
         URL: http://issues.apache.org/jira/browse/BEEHIVE-608
     Project: Beehive
        Type: Bug
  Components: Controls  
    Versions: V1    
    Reporter: Julie Zhuo
    Priority: Minor


In parent page flow,
    @Control()
    protected HelloControlBean myControl;

In the child page flow,
    @Control()
    protected GreetingsControlBean myControl;

Expecting the child page flow control member myControl overrides the one in parent flow, or
at least cause a conpiler error.

Actual: It causes the following exception and the page flow ended up inheriting the parent
myControl not overriding it.

Attatch the the repro pageflows shortly.
