Last time I had to do this, I created a POJO, configured it as a managed bean in my components faces-config.xml and offered the client to overwrite the behaviour by defining a different bean-name to use. The component would then either use its default bean-name to look up the POJO or the name the user configured. The POJO just contained pure logic... and implemented an interface the user could use to implement his own logic. regards Alexander > -----Original Message----- > From: Jesse Alexander (KSFD 121) > [mailto:[EMAIL PROTECTED] > Sent: Wednesday, April 19, 2006 1:39 PM > To: MyFaces Discussion > Subject: RE: Behaviour of custom components > > You could ask the customer for a callback-method implementing the > sort-mechanism...
