[OFBiz] Dev - Entity field validators

[Peter Goron]

Hi,

Entity engine defines in its xml schemas that a validation method can be
associated to entity field type and/or to a specific field of an entity.
e.g:
<field-type-def type="id-ne" sql-type="VARCHAR(20)"java-type="String">
  <validate method="isNotEmpty" />
</field-type-def>

I would like to know when validation methods are called because after
having done some tests and checked entity engine source code, it seems
that validation methods are never called.

Do I miss something ?

Peter

I don't have an answer, but I'm interested in this also. I've watched
for a response to this message and after a couple days without a
response, I thought I'd try to keep this topic alive.

Does anyone have experience with the type of validation Peter mentions
below?

Thanks,
Rob Riggins

This is one of those questions that I choose not to answer for time  
sake. No offense intended, but there is information about this in the  
Entity Engine Guide (see the Docs & Books page on the ofbiz.org  
site), and the question has been answered on the mailing lists a  
couple of times.

Hi David,

I would like to run field validators in GenericValue setters. Is there
any reason to not do a such thing ?

Peter,

The main reason is that validation doesn't belong in the data tier.  
In some cases it belongs in the logic tier, where it is to be more  
universally applied, and in some cases it belongs in the UI tier,  
especially when different users and in different circumstances have  
differing validation constraints.
