Hi all,
Using portal 2.6.2, I want to add new column to table 'jbp_users' and make the new column accessed from 'profile.xhtml'.

First modified the jboss-identity 1.0.0 as follow,
domain.hbm.xml

 <property
 name="unit"
 column="col_unit"
 type="java.lang.String"
 update="true"
 insert="true"
 unique="false"/>

User.java

public String getUnit();
public void setUnit(String unit);

HibernateUserImpl.java

protected String unit;
public String getUnit() {return unit;}
public void setUnit(String unit) {this.unit = unit;}

Then built new portal-identity-lib.jar for JBoss Portal.

In JBoss Portal Source, modified 3 files follow the chapter 'Reference Guide - 16.3.3. Example 3: adding new properties'.
profile-config.xml

 <property>
 <name>user.unit</name>
 <type>java.lang.String</type>
 <access-mode>read-write</access-mode>
 <usage>mandatory</usage>
 <display-name xml:lang="en">Unit</display-name>
 <description xml:lang="en">User's Unit</description>
 <mapping>
 <database>
 <type>column</type>
 <value>col_unit</value>
 </database>
 </mapping>
 </property>

identity-ui-configuration.xml

<ui-component name="unit">
 <property-ref>user.unit</property-ref>
 <required>true</required>
</ui-component>

profile.xhtml

<h:panelGroup>
 <h:outputText value="unit"/>
 <h:outputText value=" *" rendered="#metadataservice.unit.required}" />
 </h:panelGroup>
 <h:inputText id="unit" value="#{manager.uiUser.attribute.unit}" required="#{metadataservice.unit.required}"/>
 <h:panelGroup />

Finally, deploy the jboss portal.

However, what I input in the profile page for the column 'unit' has been saved to table 'jbp_user_prop' with the key 'user.unit', remainning 'NULL' in column 'col_unit' of table 'jbp_user'.

How to solve this problem?
Thanks for any help:)
