Subject Re: [jira] Closed: (MYFACES-694) t:dataTable bind calculate order error
Date Tue, 11 Oct 2005 19:33:21 GMT
Hi,

in my oppinion a bean getter shouldn't create a value, just fetch it.

if you use playlistFactory.currentUnitMPOSPlayList to create and return
the List, you should ensure that all other related getter also create
the list if the list isn't initialized before.

Generally there is no order defined to call any getter in jsf context.

Bye
