Wickersheimer Jeremy commented on OFBIZ-1141:
---------------------------------------------
I managed to write an exception interceptor.
I wrote a small utility class that does the parsing from the Exception object,
then i added 3 lines of code in StoreValue.java (the simple ethod used to
update an entity, the same can be done in CreateValue) to call the interceptor
and replace the error message when the parsing is successful.
This can effectively replace any FK violation error message (simple or multiple
K) by for example:
The party_role 'Company,CAL_ORGANIZER' doesn't exist.
I will post the patch after lunch so you can have a check, then i will add
support for localized messages.

> A lot of error messages in Ofbiz are "cryptic" for normal users. For example
> sometimes a user would trigger a database foreign key violation and as a
> result will have a quite big error message thrown at him.
> This would happen for example when you create an Agreement then gives both a
> Party Id To and a Role Type Id To that doesn't match.
> In that case the error is something like:
> ERROR: Could not complete the Create an Agreement
> [file:/home/jeremy/bertelsmann/dgerp/applications/accounting/script/org/ofbiz/accounting/agreement/AgreementServices.xml#createAgreement]

> It is fine for a developer who can understand that, but not for a user.
> I agree that with some hacking or better design in the forms it would be
> possible to avoid that kind of error, but the idea would be to be able to
> catch that and replace the error we something more understandable, for
> example:
> ERROR: the "Party Id To" doesn't have the "Role Type To Id" you entered.
> Or better:
> ERROR: the "Party Id To: Admin" doesn't have the "Role Type To Id: Person".
> Possible values for the Role Type are : "..."
> I know that such a feature cannot be implemented in the framework directly
> because errors are context sensitive, so it would have to be done in the
> Service XML definition.
> Perhaps some new methods could be added in simple-methods to make that task
> easier ?
