Re: Data binding expression with list items

[Dirk Möbius]

I think in Pivot 2.0 it would be possible with a little script trick:
  <script>
    function myListAt(index) {
      return myObj.myList[index];
    }
  </script>

  <TextInput textKey="${myListAt:2}/>

But I guess that you don't want to use a hard wired constant there  
(don't you?), rather something like:

  <TextInput textKey="${myListAt:otherList.selectedIndex}/>

It isn't currently supported, though it would be trivial to add. I'm  
curious about the use case, though. It seems a bit fragile to rely  
on a numeric index, but maybe there is a valid use for it.

Hi,

Is it possible to have binding expressions that refer to list items  
using index accessor such as the following one (myList being of  
type java.util.List) ?

...
<TextInput textKey="myObj.myList[2]"  />
...

thanks in advance
