How to pass a parameter via another bean object inside a method called from <f: event listener = "...">

How can I pass a parameter through another bean object inside a method called from <f:event listener="...">

?

I am trying to pass a parameter generated by another bean inside a method showData()

to be called when using

<f:event listener="#{myTransformerBeans.showData}">

      

        
        
        
      

    

The parameter will be #{myDataBean.myId}

.
