I have added a new attribute in one existing type. my attribute is available in model class and also in jalo classes. But when i checked in HMC it is not showing the attribute in admin tab. As well as in type's XML configuration does not have that attribute in HMC.
steps done by me: added my attributes in items.xml where other attributes also added earlier. after this i have run ant clean all and checked the model class and attribute is there in model class.
used below code for adding my attribute in items.xml:
<itemtype code="Customer" autocreate="false" generate="false">
<attributes>
<attribute qualifier="OosFlag" type="java.lang.Boolean">
<description>OosFlag</description>
<defaultvalue>Boolean.TRUE</defaultvalue>
<modifiers read="true" write="true" search="true" optional="false"/>
<persistence type="property"/>
</attribute>
</attributes>
</itemtype>
You need to update your type-system in the database. That means you need to do an UPDATE in the admin-console.
The generated classes are only templates. The important point is what in the database stands.
P.S. you should start your attributes always with a lower-case.
