CLONE - seam:component intercept uses Seam standard rules by default
--------------------------------------------------------------------
Key: JBSEAM-4743
URL: https://issues.jboss.org/browse/JBSEAM-4743
Project: Seam
Issue Type: Bug
Components: Spring
Reporter: Magnus Heino
Assignee: Michael Youngstrom
Fix For: The future
From spring-seam-2.0.xsd, intercept:
Determines whether Seam interceptors should be wrapped around a bean, by overriding
Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a
singleton" default.
This bean
<bean id="processRepository"
class="se.lantmateriet.wfl.dataaccess.WsProcessRepository">
<constructor-arg value="http://localhost/avtal/avtalservice.asmx"/>
<seam:component/>
</bean>
fails like this:

If I change <seam:component/> to <seam:component intercept="false"/>
everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?
