I haven't really looked into the callbacks before, so I am curious and
taking a peek. In Cayenne Modeler there is a "Callbacks" tab when you
select the ObjEntity. (These comments will most likely apply to the
"Listeners" tab for the ObjEntity and DataMap as well.) There is a
Callback Type popup and then you click the Add Method button (which
looks dimmed out to me, like it is disabled). Below them is a table
with a single Method column. (Wish I could do screenshots here.) If
you add a pre-persist callback (select it then click the Add Method
button) and then change the Callback Type popup to post-persist, it no
longer shows the pre-persist callback method. This seems awkward to
me.
I'd suggest removing the Callback Type popup from where it currently
is and making the table below have two columns (Method, Callback
Type). Clicking the Add Method button would add a new row to the
table and the Callback Type column would contain a popup or pulldown
that the user could select. This would allow the user to see all of
their callbacks at the same time instead of hiding them. It could
default to pre-persist (along with the default onPrePersist method
name). If they change the Callback Type and haven't edited the method
name (it is still at the default), then change the method name to the
default for the selected Callback Type. If they have changed it,
don't alter the method name.
Thoughts?
Thanks!
