Question

i have a page called page1.jsf which contains one parameter. i have a command button which contains the param. On clicking the button, it must return to page1.jsf together with whatever parameter i pass.

<h:commandButton action="#{myBean.DoSthng}" value="Something" >
 <f:param name="p1" value="sthng"></f:param>
 </h:commandButton>

How would i pass this parameter to page1.jsf itself?

In the faces-config.xml – managed Bean, i set it like this

<managed-bean>
  <managed-bean-name>myBean</managed-bean-name>
  <managed-bean-class>com.MyBean</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
  <managed-property>
    <property-name>p1</property-name>
    <value>#{myBean.p1}</value>
  </managed-property>
</managed-bean>

and this is giving me an error.

Can you all help me please.

EDIT

From page1 i have to pass a value from an action to backing bean. The backing bean should redirect me back to page1 but with different contents!

Answer 1

You put your param in hidden field and it will be available

<input type="hidden" id="sl" name="sl" value="#{param.sl}"/>

And then you can use it

${param.sl}
