[jboss-user] [JBoss Seam] - Seam CR1.2 component name and precedence
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(a)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
