Answer 1

Your problem is caused by having immediate="true" on the <h:commandButton>.

<h:commandButton ... action="#{bean.action}" immediate="true" />

It will skip processing of all input fields which doesn't have immediate="true".

Just get rid of it.

<h:commandButton ... action="#{bean.action}" />
