I have a datagrid that has an ArrayCollection of objects as the
dataprovider. Some of the columns are editable and some are not.
When I edit a column that is editable and finish editing (either by
tabbing out, hitting enter, or click out of focus) I get a big long
nasty error that looks like this:
Error: Unknown Property: '4294967295'.
