Hi there,

I am getting this error for some of the a4j tags any inputs to deal with errors are greatly appreciated.

<a4j:actionparam> Tag Library supports namespace: http://richfaces.org/a4j, but no tag was defined for name: actionparam

I am using richfaces 4.1 m4.

Thanks

Hi,

a4j:actionParam in RichFaces 4 was renamed to a4j:param. You can find more information in Component Reference (http://docs.jboss.org/richfaces/4.1.X/4.1.0.CR1/Component_Reference/en-US/html/).

Hi Pavol,

Thank you so much for your reply. It worked for me but now I am facing problem for accessing client variable in the value attribute of a4j:param.

my code is like this,

<h:form id="formid">

<h:outputScript>

                                                               function radiomethod(){

          return document.getElementById("formid:radioValue").value;

                                                             }

                                                  </h:outputScript>

<h:inputHidden id="radioValue" />

<a4j:jsFunction name="functionName" action="#{mybean.actionmethod}" >

                                                             <a4j:param name="param" value="radiomethod();" noEscape="true" />

                                                  </a4j:jsFunction>

</h:form>

Can you please point how can I access the client variable from in the value attribute.

Thanks in advance.

Thanks

Do you mean how to access that value from the bean? If yes, then you need to assign that value to some property of your bean using assignTo attribute of a4j:param. Moreover, the attribute  value should contain radiomethod() - without semicolon.

You can find more information about a4j:param in the Component Reference [1].
