Passing Parameters in action listener event in a custom tag

Question

In continuation of building a custom tag, all the processes have been done and are working accurately except passing parameters to beans method. i have tried but unable to pass the parameters, following is the code.

web.xml

    <context-param>
        <param-name>facelets.LIBRARIES</param-name>
        <param-value>/WEB-INF/pinnacleTags.taglib.xml</param-value>
    </context-param>

tabib

<?xml version="1.0" encoding="UTF-8"?>
<facelet-taglib>
    <namespace>pinnacleTags/facelets</namespace>
    <tag>
        <tag-name>PinnacleCombo</tag-name>
        <source>buttonPanel.xhtml</source>
        <attribute>
            <name>textBoxValue</name>
        </attribute>
        <attribute>
            <name>caption</name>
        </attribute>
        <attribute>
            <name>btnCaption</name>
        </attribute>
        <attribute>
            <name>textBoxWidth</name>
        </attribute>
        <attribute>
            <name>btnHeight</name>
        </attribute>
        <attribute>
            <name>btnWidth</name>
        </attribute>
        <attribute>
            <name>actionListenerBean</name>
        </attribute>
        <attribute>
            <name>actionListenerBean</name>
            <method-signature>void actionListener(javax.faces.event.ActionEvent)</method-signature>
        </attribute>
        <attribute>
            <name>actionListenerMethod</name>
            <method-signature>method-signature="java.lang.String action(javax.faces.event.ActionEvent)"</method-signature>
        </attribute>
    </tag>
</facelet-taglib>

the component

        <ui:composition> 
            <div>
                <h:outputLabel value="#{caption}" />
                <p:inputText value="#{textBoxValue}" style="width: #{textBoxWidth}; " />
                <p:commandButton type = "submit" 
                                 value = "#{btnCaption}" 
                                 actionListener="#{actionListenerBean[actionListenerMethod]}"
                                 style="height: #{btnHeight}; width: #{btnWidth};" />
            </div>
        </ui:composition>

and finally the useage

            <pt:PinnacleCombo id="clientID" 
                                textBoxValue="#{customTags.clientID}"
                                caption="Client ID: " 
                                textBoxWidth="150px" 
                                btnHeight="35px" 
                                btnCaption="Press"
                                actionListenerBean="#{customTags}"
                                actionListenerMethod="btnPressed"/>

I donot know how to pass parameters to the menthod, pls suggest.

Answer 1

finally as @Selaron suggested, the custom tag, after using omnifaces, is

        <ui:composition> 
            <h:outputLabel value="#{caption}" />
            <p:inputText value="#{textBoxValue}" style="width: #{textBoxWidth}; " />
            <o:methodParam name="method" value="#{actionListenerBeanMethod}" />
            <p:commandButton type = "submit" 
                             value = "#{btnCaption}" 
                             actionListener="#{method}"
                             style="height: #{btnHeight}; width: #{btnWidth};" />
        </ui:composition>

and the function call was simple

actionListenerBeanMethod="#{customTags.btnPressed('Value Passed')}"

Thanx @Selaron for help.
