                 Key: JBSEAM-2141
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2141
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: EL
            Reporter: Mikhail Grushinskiy


Support for EL without reflection for better JSF performance.

The idea is to add a new tag to declare types of the variables used on a page and use this type information
to compile EL expressions into byte-code during initialization (deployment)

Ex:
If the page contains at the beginning

<s:typedef var="myBean" class="com.company.package.Bean" />

then all EL expressions can be compiled into bytecode at initialization time (and no reflection will be used for myBean access.

<h:outputText value="#{myBean.subBean.property}" rendered="#{myBean.renderText}" />


Some examples of implementation of compiled EL can be found here

This should help much with JSF performance issues

Thanks
