<window id="win1">
    <label id="lab1" value="myValue" />
    1:${lab1.value}
    <window id="win2">      
       <label id="lab1" value="yourValue" />      
        2:${win1.lab1.value}
    </window>
</window>

Please help. After a couple of hours googling I still cannot find out the way to make reference to a component in the parent idspace in a zul file. For example, in the above code, what is the way to access lab1.value in win1 from win2? ${win1.lab1.value} doesn't work. It seems easy in java by using "getFellow()" or Path.getComponent("x/y"). [direct access to components in the parent IDSpace with unique ids is no problem].
