>             Project: Apache Flex
>          Issue Type: Bug
>          Components: ADG:Display
>    Affects Versions: Apache Flex 4.12.0
>            Reporter: Justin Mclean
>
> This is a regression from 4.11. It a minor issue but as it a regression I put it at major.
> A ADG column with no dataField and no data renderer defined will display "[object Object]". It would display blank in 4.11 and earlier.

> Work around is to define the dataField, add a labelFuction, add a toString method to the object or use a real item renderer.
