a4j commandLink doesnt work properly when using f:params and disabled condition, The link doesnt reRenders the value the first time the condition its not fullfilled
--------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: RF-7476
                 URL: https://jira.jboss.org/jira/browse/RF-7476
             Project: RichFaces
          Issue Type: Bug
          Components: component-a4j-core
    Affects Versions: 3.3.1
         Environment: JBoss Seam 2.1.1 GA, OC4j Server
            Reporter: Javier Quirante


When we have an a4j commandLink that pass parameter via f:parameter, if the parameter passed , is on the disabled condition of the a4j commandLink, the button doesnt reRender the first time its fullfill the disable condition

For instance if we have the button

------------------
<a4j:commandLink  value="Hello J" reRender="block" bypassUpdates="false" disabled="#{jiraHome.disabled}">
     <f:param name="firstName" value="Javier"/>
</a4j:commandLink>
--------------

with pages.xml
-------------
<param name="firstName" value="#{jiraHome.firstName}"/>
-------------

that reRenders the panelGrid "block" whith an h:inputText
--------------
<h:panelGrid columns="1" id="block">
     <h:inputText id="value"
          value="#{jiraHome.firstName}"/>
</h:panelGrid>
----------------

And in the backup bean the condition is
-----------
public boolean getDisabled(){
    return firstName!=null && "Javier".equals(firstName);
}
-----------------
(if the parameter passed is "Javier" --> disable the commandLink)

If you click the button its never write "Javier" in the input Text. But the first time you click, when the commandLink is enabled, it shouds
reRender the inputText with the text "Javier" becuase its not still disabled.
Next times is would be ok the commandLink doesnt work because is disabled because of the condition.

If you try with h:commandLink its works like that.
I try with scopes REQUEST and CONVERSATION on the Bean and doesnt work neither

Thanks in advance
