What's the appropriate way to modify ViewEntities?

[Patrick-4]

What's the appropriate way to modify a viewEntity?  I have a
viewEntity, FacilityAndContactMechAndAddress, and it has 3 primary
keys, but they don't seem to work as expected.   I tried the code
below, but it says bad primary key.   Am I taking the wrong approach?
Also do you think I should do this at the java service level or the
simple-method level?

<!-- this didn't quite work, bad primary key (but this works if I
change entity-name to Facility for facility fields)  -->
<set field="lookupPKMap.facilityId" from-field="parameters.facilityId"/>
 <find-by-primary-key entity-name="FacilityAndContactMechAndAddress"
map="lookupPKMap" value-field="facilityId"/>
 <set-nonpk-fields map="parameters" value-field="facilityId"/>
<store-value value-field="facilityId"/>

Thanks
Patrick

Hi Patrick

From memory, a view entity will only be modifiable if the primary keys for all included entities are present.

As a best practice, you should generally only perform write/update/delete operations on entities via the services available, doing so will ensure that all related SECAs are run.
