Re: JSF dataTable Binding

[Simon Kitching]

Once you have a binding to the UIData component, you can call the 
getRowIndex method on it.

However using binding and accessing UIData objects directly is not 
generally necessary. I suggest you find a book or article on using JSF 
tables to see if there is a better solution for whatever it is you are 
trying to achieve via this "weekIndex" value.

I could make it a UIData I guess.
But because the "Value" in the table was a list of integers, I wanted to 
bind the value over which I am iterating to my bean.
I also tried

<x:inputHidden value=#{row} binding="#{pgb.weekIndex}"/>

Is that not supported? is there a better way of doing it?
I assumed that because my value was a List<Integer>, that the variable 
"row" would be an Integer, and I could bind it to my bean.

Thanks

    The binding attribute must point to a method like this:
       public void setXXX(UIComponent component);

    In the case above, a UIData object will be passed to the method, ie the
    object implementing the x:dataTable.

    I have no idea what you are trying to achieve by binding to some
    Integer..
