Hello!
I have a problem creating a to-many relationship using Castor. The framework
says my Collection-Getter Method should not return the
Collection-Implementation I specified, but the Type of the elements in the
collection (like it was no to-many reference at all). Can anybody tell me
what I did wrong?
mapping.xml:
<class name="UARoles"
identity="rolesID" access="db-locked">
<description>UA Roles</description>
<map-to table="ADS_RoleTables" xml="roles" />
<field name="roleChanges" type="UARoleChange" required="true"
collection="arraylist">
<sql many-key="ROLES_ID"/>
<xml node="element"/>
</field>
</class>
<class name="UARoleChange"
identity="changeID" access="db-locked" depends="UARoles">
<description>UA Role Change</description>
<map-to table="ADS_RoleChanges" xml="rolechanges" />
<field name="uARoles" type="UARoles">
<sql name="ROLES_ID" />
<xml name="uaroles" node="element" reference="true"/>
</field>
</class>
Error:
org.exolab.castor.mapping.MappingException: The return type for method
public java.util.ArrayList UARoles.getRoleChanges() does not match the
declared field type UARoleChange
