Thanks for this short reply.
But this serialization is a little bit problematic for me...
I have a site with two different backing beans and a command button. The
command button calls method A.1 from bean A, the site is reloaded (the
method changes some properties of bean A) and all properties of A are
renewed within the jsf site. Additionally A.1 changes some properties of
bean B but those properties are not renewed within the view.
So I tried to use component binding with bean B but this does not work
because I can not use HtmlOutputText with my bean B because it is not
serializable...?
<h:commandButton value="action" action="#{A.1}" />
<h:outputText value="#{A.property}"/>
<h:outputText value="#{B.property}"/>
