Param Name in pages.xml? What am i doing wrong?

[jnusaira]

So basically we are going to have two seperate xhtml pages.

They will call the same back end service the only thing they really differ on is type.

So ... i was trying this -

<page view-id="/workStreamScheduler.xhtml" action="#{scheduleService.edit}">
          <param name="schedule.workStream" value="AUTOMATED_REGISTRATION"/>
</page>

And on the service i tried it as a requestParameter, an In etc.

The object gets populated just fine but when i go to the page i have this error -

model validation failed:javax.el.PropertyNotWritableException: Illegal Syntax for Set Operation 

Any idea whats going on?

The value attribute must point at a bidirectional EL expression.
