Hi Simon,
since you only want to display the details of the selected item, the
list's selection seems like the obvious choice as a binding source.
"value" would be the target on the text field. Assuming your model
objects have a "detail" property, you could do something like this:
list.getSelection().bind("[0]", textField, "value", {
converter : function(data) {
return data.getDetail();
}
});
One caveat: The "bind" call will immediately try to apply the value to
the target property. If you don't use the "one" selectionMode for the
List, there won't be an initial selection, so "data" in the converter
will be undefined. So either use the "one" selection, or add a check to
the converter.
Regards,
Daniel
