Hi all,
I've got two questions
1) Are initial values set with server code propagated to clients when
an object is created on the client?
The following url...
http://cwiki.apache.org/confluence/display/CAY/Setting+Initial+Values
... suggests using "public void setPersistenceState(int)" for setting
initial values when state is NEW. I assume this is the equivalent of
EOFs awakeFromInsertion(EOEditingContext).
The above method is not triggered on the client (i.e., it's never
called) - so my question is whether (in having this code on the
server) these values will be available initially to the client
context or not?
2) Object modifications
DataContext has event subjects DID_COMMIT, DID_ROLLBACK, WILL_COMMIT
subjects. Great. Where might I find what objects are available via
these notifications?
EOF's delegate has editingContextWillSaveChanges(EOEditingContext)
where if you throw an exception it will abort the save for the
context. How might a listener of the WILL_COMMIT changes event
achieve this? Note: this is not a question about validateForSave.
More importantly - what's the best mechanism to (post validation but
pre actual commit) of actually making some final adjustments to an
object. e.g., something simple such as dateModified field. I know we
could put this into validateForSave but we call this many times prior
to saving on the server - actually whenever someone makes a change in
the gui (in order to highlight what might prevent saving the object).
setPersistentState seems to be only called one time if the state of
an object changes. Would the best way of keeping things like
dateModified and other calculated fields up to date be to overload
writeProperty?
Much appreciated. Thanks.
with regards,
