I am having an issue with using Seam with passed in Action Parameters in EL. I
am tied to WebLogic right now, and hearing about the EJB3 issues that Seam has,
I just want to use the UI features of Seam in order to pass parameters to
method calls in the EL. I am using Seam 2.0 GA, Facelets 1.1-13, and RichFaces
latest release along with the Sun RI Implementation of JSF.
In a facelets page I have the following code:
<ui:composition>
| <f:view>
| <s:fragment rendered="#{SecurityManager.isAllowed(View_Position)}">
This is throwing an exception:
com.sun.facelets.tag.TagAttributeException:
//C:/dev/workspace/AppName/WebContent/WEB-INF/tabs/position.xhtml @15,68
rendered="#{SecurityManager.isAllowed(View_Position)}" Error Parsing:
#{SecurityManager.isAllowed(View_Position)}

It seems that the FaceletViewHandler is still being used to interpret EL
expressions. I find documentation relating to Seam 1.1 that refer to a
SeamFaceletViewHandler, but that seems to be missing from Seam 2.0. Is there
something glaringly obvious I am missing? Please let me know if you need
further information regarding my configuration or anything else.
Thanks!
