[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-3633) @RequestParameter fails in mixed JSF/non-JSF applications

Tim Otten updated JBSEAM-3633:
------------------------------

    Description: 
If an application includes both JSF pages and servlets, then @RequestParameter injection cannot succeed consistently.

@RequestParameter injection relies on a "Parameters" component. There are two alternative implementations of this component:

 * org.jboss.seam.faces.Parameters which supports JSF pages
 * org.jboss.seam.web.Parameters which supports traditional servlets

Only one of these implementations can be used at run time. If the developer or deployer chooses to use the JSF variant, then @RequestParameter injection will break for servlet-based pages. If the developer instead chooses the servlet variant, then @RequestParameter injection will break for JSF-based pages.

(Note: The relevant code in trunk [r9424] appears to be the same as the code in 2.0.2.SP1, so newer releases are probably affected.)


  was:
If an application includes both JSF pages and servlets, then @RequestParameter injection cannot succeed.

Currently, there are two alternative classes which resolve request parameters:

 * org.jboss.seam.faces.Parameters which supports JSF pages
 * org.jboss.seam.web.Parameters which supports traditional servlets

Only one of these classes can be used at run time.

(Note: The relevant code in trunk [r9424] appears to be the same as the code in 2.0.2.SP1, so newer releases are probably affected.)
