Validation Service
Validation Service allows you to define validation rules for an entity and display customized error messages if the validation fails.
The validation code runs when the user is saving or modifying an entity. It runs after
cleansing and any other LCA actions. It is for new entities, data change requests, and
for both mobile and desktop clients. If the entity fails the validation tests, it is not
saved. Validation Service displays field-by-field messages as well as messages that
depend on more than one field. For example, if there is more than one address but only
one can be primary, then Validation Service can test for multiple primary addresses and
one address is, in fact, primary. If the user tries to make two addresses primary, then
Validation Service displays a customized error message. An appropriate message appears
in the overall messages.
Note: The validation message includes a new field,
objectParentUri which is the URI of the parent
attribute.Warning: Validation Service can work with
ov=true/false but it
is better not to send the URIs of ov=false to user interface values
because it may lead to unpredictable behavior.
