Dynamic left menu plus different action on each....

Question

Hi everyone. I am making a dynamic left menu using a datatable and links in it.
I am using an xml file to read all the attributes associated with a link like label, id etc.
<h:dataTable
                    value="#{sampleMB.menu}" var="menu">
<h:column>
<h:commandLink value="#{menu.label}" onclick="#{menu.onclick}" styleClass="subItem" action="??????????"></h:commandLink>
</h:column></h:dataTable>
The problem is how to assign the action from xml file here because the action attribute accepts a method with
syntax String mathodname(). So I am not able to put something like #{menu.action} where action is a variable
whose value I can read from xml.

Answer 1

Thanks for the reply but can u please elaborate a bit more with some code. I hope u've understood my problem clearly.
You can directly write a string in action like ::
<h:commandButton value="Submit" action="myaction"></h:commandButton>
where myaction can be mapped to anything in your navigation rules in faces-config
But you cannot do something like this ::
<h:commandButton value="Submit" action="#{sampleMB.strMyAction}"></h:commandButton>
where strMyAction is actually a String variable. It gives an error like "Expression must be a method expression but is a value"
See I am reading all the attributes associated with the commandButton form an xml file. So which action to invoke is also there in the xml. Now all these values including the action can be put in the String variables. The problem is how to invoke the method represented by that action String litral.
