Dear Group,
I am using GWT Requestfactory for accessing server-side entities (JPA
entities).
For validating data I apply JSR 303 validation.
Here is my situation:
1. On Persist everything works fine. Entity is validated on pre-persit and
in case of constraint violations the "onConstraintViolation(..)" is called.
Persisting entities works fine.
2. Problem occurs when I try to edit an existing entity using "entity2 =
request.edit(sampleEntity);", write new data to it and send it to the
server.
In that case a ConstraintViolation is thrown (probably this should be the
case) but "onFailure(...)" method is called .... instead of the
"onConstraintViolation(..)"?
What could be the reason for this??? Why is the "onConstraintViolation(..)"
not called when updating the entity?
The error message is displayed below:
Thank you in advance:
Nermin
