    Seam CR1.2 component name and precedence

    Venkatesh BR Newbie

      hello,

      We have just upgraded our application from Seam 1.1 Beta 2 to jboss-seam-1.1.0.CR2. From then on i am getting this exception when the classes are being scanned by seam during server startup.

      emailSession is an application component defined in components.xml. I pass some properties to this component through components.xml



       <component class="com.OutboundEmailSession">
       <property name="host">emalhost</property>
       <property name="fromAddress">me@test.com
       </property>
       <property name="fromName">My Name</property>
       </component>
      


      This error disappears when I remove this component declaration from components.xml
      I guess when i declare my component in components.xml the component is found twice by seam during initialization

      This was working fine when in Beta 2. Is there a change in component precedence which i have to explicitly set for using CR1.2.

      regards
      Venkatesh
