This is part of a servlet/JSP app, but I've simplified the problem down to a simple test case and posted it here as a core Java problem.
I have an ArrayList of beans. How do I access the properties of those beans?
The error is "array required, but java.util.List<SimpleBean> found". That's not very helpful. Array required where? I'm reading from an array element. I want the bean and it's properties, not another array.
I know the answer is going to be a forehead-slapper, but I've struggled with this long enough. Can someone please point out the obvious answer for me?
Thanks

You're accessing an ArrayList as if it were an array.
Try: myList.get(0) to retrieve the bean.

Doh! Told you it was going to be a forehead-slapper. Both of these work:
Thanks for the help.
