Hi All,

We have an PR for GTNPORTAL-3530 https://github.com/gatein/gatein-portal/pull/895

This PR help to overwrite mapping file HibernateIdentityObjectAttribute.hbm.xml that map almost attributes to nvarchar

But beside firstName, lastName, and displayName. Currently, user can also put UTF-8 to fields when creating new Group and Membership.

For example, I create a new Group with GroupName: Tuyến --> It raises exception in the server log. I guess this problem also comes from UTF-8 issue with nvarchar

The same issue with Membership:

MembershipName: điểm

Description: mô tả

--> Exceptions raised:

[http-bio-8080-exec-11] ERROR portal:UIPortalApplication - Error during the processAction phase

java.lang.NullPointerException

My question is: we should also map those attributes to nvarchar column ? Or we add validator and don't allow user to create Group and Membership with UTF-8 name ?

Hi Bolesław,

Thank you for your answer,

I saw the way we did with Sysbase and i think we can fix this issue in a similar way.

I'm going to continue working on this issue.

Thank you again,

Nguyen The Tuyen.

Hi,

I'm not a DB expert however from what I see your observations are correct:

http://stackoverflow.com/questions/176514/what-is-the-difference-between-char-nchar-varchar-and-nvarchar-in-sql-server

As a temporary workaround it should be doable to simply alter the table
and change the column type.

We'll need to look at the issue - I don't have a fix for hibernate
mappings on top of my head. If there is a need for special mappings just
for SQL Server 2008 it is doable with current setup - we already have
separate hibernate mapping files for Sybase for very similar reason.
