When does Facelet's re-evaluate ui:fragment rendered expression?

Hi-

I'm using <ui:fragment rendered="#{myBean.rendered}">...
in my page.  The business logic behind myBean.isRendered() is a fairly
expensive DB query.  When I submit a form that includes that fragment,
the EL for the rendered attribute is being re-evaluated during the Apply
Request Values phase.  Is this expected?

I assumed that the rendered attribute
would only be evaluated during the Render View phase, since this is the
only time you'd want to toggle this attribute.

I don't want to store myBean in session/conversation/view
scope.  Is there another way that I can prevent my method being called
during the post-back?

Thanks for any tips.
