DataList requires form elements to be in column to be properly processed

When using the DataList component to iterate over a list of items, form elements (such as checkboxes, textfields, etc) do not get properly populated in the model on submit unless the items are contained in an otherwise uneccesary column.

I found out about this bug by stepping through the code and realizing that DataList extends the UIData component which currently only will process children of a column. DataGrid uses the column metaphore.

The DataList should not require the use of a column becuase it does not make sense for a DataList.
