[Andromda-user] [Hibernate cartridge] [updates on a CLOB that was only read]

["Widas" (AndroMDA Forum)]

I know that this is an old thread, but I had the problem with update-on-read for Entities holding a clob type,too.

Obfuscator's recommendation works here.

This is what I do:

in mda/src/main/config/mappings, I created a file "HibernateExtensionMappings.xml" with the following content:


<?xml version="1.0" encoding="ISO-8859-1" ?>
<!--
 Fixes/extends original AndroMDA Hibernate Mappings, which you find in HibernateTypeMappings.xml
-->
<mappings name="HibernateExtension">
   <extends>Hibernate</extends>
    <mapping>
        <from>datatype::Clob</from>
            <!-- Map to text, as the HibernateStringClobType causes an update after read
                 if the attribute is NULL
                   See http://galaxy.andromda.org/forum/viewtopic.php?t=4583 -->
        <!--to>org.andromda.persistence.hibernate.usertypes.HibernateStringClobType</to-->
        <to>text</to>
    </mapping>
</mappings>



And in mda/src/main/config/andromda.xml, change to:

        <property name="hibernateTypeMappingsUri">file:${conf.dir}/mappings/HibernateExtensionMappings.xml</property>



With this, the update-on-read problem is fixed here.
Tested with AndroMDA 3.2
