Re: How to implement custom "find" methods in GWT+roo scaffolding app

As far as I see no one is going to answer me.
I found https://jira.springsource.org/browse/ROO-1595 and if I got
them right there is NO custom finder methods available at this time
(it's still openned).
Without them I can't use generated Request object and possibly all
over stuff.
If you don't want to explain just say am I right or not. If I can't
use custom finder methods I just leave roo and do everything by hands.
