[seam-dev] PARAM_BUILD_BEFORE_RESTORE

[Dan Allen]

Hey guys,

During the panel discussion last night as JSF One, I learned about an
undocumented feature in Facelets, which may be just the solution you
were looking for, Christian, regarding stale views on a login or other
public form page. Facelets has the ability to build the view during
the restore view phase if on postback the view state couldn't be
found. You simply set the context parameter PARAM_BUILD_BEFORE_RESTORE
to true. As it turns out, this is going to be the default behavior in
JSF 2.0 to avoid the very problem that you observed, that a stale
login page would reject a login, throw up a confusing message, and ask
the user to try again.
