Leszek Kowalski commented on JBSEAM-1015:

OK, sorry for that.

In Seam 1.1.6 there were at least two ways to disable component:
<component class="component.className" installed="false" /> and
<ns:componentName installed="false".

Since 1.2.0 both don't work (or am I missing something?). Do you have any plans to support this functionality in future releases? I need this to disable exceptionFilter which is installed by default (unfortunately I'm forced to use spring managed transactions which doesn't play nicely with seam - http://www.jboss.com/index.html?module=bb&op=viewtopic&t=104430).

>             Project: JBoss Seam
>          Issue Type: Feature Request
>          Components: Core
>    Affects Versions: 1.2.0.GA
>         Environment: Seam 1.2.0Patch1, Jetty 5.1.12
>            Reporter: Leszek Kowalski
> Since rev 1.152 of Initialization.java (JIRA-897) it is not possible to disable built-in Seam component in components.xml (using <ns:componentName installed="false").
> Here is problematic code:
>                //if this class already has the @Name annotation, the XML element 
>                //is just adding configuration to the existing component, don't
>                //add another ComponentDescriptor (this is super-important to
>                //allow overriding!)
>                if ( nameAnnotation!=null && nameAnnotation.value().equals(name) )
>                {
>                   Install install = clazz.getAnnotation(Install.class);
>                   if ( install.value() )
>                   {
>                      className = null;
>                   }
>                }
> For all components with @Install annotation className is set to null and installComponentFromXmlElement() cannot create "not-installed ComponentDescriptor".
