RichFaces4 rich:componentControl x rich:component

[edilmar]

This code arises an exception "<rich:componentControl> The event name is not defined":

  <a4j:commandButton id="Pedido_buttonSaldo" value="Saldos"

                     execute="Pedido_numero" render="messages,Pedido_numero"

                     title="Mostrar o saldo calculado do pedido"

                     status="statuspedido">

    <rich:componentControl target="panelPedido_buttonSaldo" operation="show"/>

  </a4j:commandButton>

But this code works fine:

  <a4j:commandButton id="Pedido_buttonSaldo" value="Saldos"

                     execute="Pedido_numero" render="messages,Pedido_numero"

                     title="Mostrar o saldo calculado do pedido"

                     status="statuspedido"

                     onclick="#{rich:component('panelPedido_buttonSaldo')}.show()"

                     >

    <!--

    <rich:componentControl target="panelPedido_buttonSaldo" operation="show"/>

    -->

  </a4j:commandButton>

The code with rich:componentControl worked fine in RF3.3.3.

The strange is that the code to hide the panel works fine in RF4.0.0 with rich:componentControl:

  <rich:popupPanel id="panelPedido_buttonSaldo" width="350" height="120">

  <f:facet name="header">

    <h:panelGroup>

      <h:outputText value="Consulta de Saldo do Pedido"></h:outputText>

    </h:panelGroup>

  </f:facet>

  <f:facet name="controls">

    <h:panelGroup>

      <h:commandLink value="[#{msgBotoes['labelFechar']}]" id="hidelink">

        <rich:componentControl target="panelPedido_buttonSaldo" operation="hide"/>

      </h:commandLink>

    </h:panelGroup>

  </f:facet>

  <h:outputText escape="false" value="#{pedido.saldo}"></h:outputText>

</rich:popupPanel>

And if I change the a4j:commandButton for h:commandButton, all componentControl works fine! But no execute/render works, off course.

componentControl is re-implemented as JSF 2 behavior. so add event="click" to specify event which should invoke operation

[edilmar]

Why do h:commandLink/h:commandButton work without event="click" and a4j components need this aditional property?

[ilya_shaikovsky]

because ClientBehaviorHolder interface implementors supposed to provide default event for behaviors. And some RF components misses it https://issues.jboss.org/browse/RF-10941

B.t.w. actually I think that specifying event really good practice even when have default ones.. It makes code more readable for more complex components than just button and link.
