Unable to pass parameters to h:commandButton

[vgs]

I am trying to pass parameters while executing h:commandButton. The parameters are not propagated like it does for s:button. So, how to pass f:param for a h:commandButton. My code looks likes this

    <h:commandButton action="#{books}"value="#{Save}">
        <f:param name="bookId" value="#{book}"/>
    </h:commandButton>

What exactly doesn't work? Did you use @RequestParameter in your bean?

This is the way we used -
<ice:panelSeries var="icon">
<ice:commandButton id="name" value="#{icon.name}" action="#{Test.execute(icon)}">
     <f:param name="iconId" value="#{icon.id.iconId}" />
</ice:commandButton>
</ice:panelSeries>

Hi Shravan,

there are two way to catch the your f:param.

Either you annotate a variable with @RequestParameter in your bean:

@RequestParameter
private Long iconId;
@Out
private Icon icon

//do some action
public void execute() {
    icon = entityManager.find(Icon.class, iconId);
}

Or you declare the parameter within your page.xml

<?xml version="1.0" encoding="UTF-8"?>
<page view-id="/receiver.xhtml"
      xmlns="http://jboss.com/products/seam/pages"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://jboss.com/products/seam/pages   
      http://jboss.com/products/seam/pages-2.2.xsd">
    <param name= "iconId"/>

</page>
