Hi,
Given a new element (E.g., a CreateObjectAction), and an existing element
(E.g., Activity), I need to set the CreateObjectAction as a child or owned
element of the Activity. I tried using
Activity.getOwnedElements().add(theCreateObjectAction) and also
allOwnedElements().add() but I get a UnsupportedOperationException. Need
help on the right API to use.
Thanks,
Francis

Francis,
The ownedElement and allOwnedElement features are derived unions, and hence,
by definition, read-only. Try using Activity#createNode(String, EClass), or
if the action has already been created, you could add to the list returned
from Activity#getNodes().

Francis,
To figure out if the collection you would like to add items to is derived
( and you actually have a life and don't want to figure this out from the
superstructure spec) then you can have a quick look at the interface at the
getter for the '@model' tag where derived=true. Derived unions calculate
their values from other properties that are defined to subset it. You can
also find subset information in the interface ( new in the M3 milestone ).
Cheers,
- James.
