Hi Simon,
Thanks for the answer. I've solved my problem. I changed the backing bean
from "request" to "session" in the faceconfig.xml. It runs.
Thanks again.

I think you have a misunderstanding about the "rendered" attribute.
Setting this to false does not "make the component invisible in the
rendered html", it does not output the component into the html at all.
If you just want the field to become invisible to the user, but actually
be present in the page, then I suggest either:
(1)
value="#{myBean.searchitem2"
rendered="#{mybean.searchLabel == 2}"/>
value="#{myBean.searchitem2}"
rendered="#{mybean.searchLabel != 2}"/>
which ensures that if the inputText is not rendered, then a hidden field
is generated instead that contains the same value
or
(2)
style="#{myBean.searchitem2Style}"/>
where method getSearchitem2Style returns "display:hidden" if the input
should not be visible.
Regards,
Simon
