ArcSDE layers does not draw but can be selected

[ModyBuchbinder]

Hello

We have some strange layer in ArcSDE (Oracle11g, ArcSDE 10.1) that does not draw on screen without any error message (single symbol).

When you select the features the selected features is drawn in the selected color only.

The attribute table looks fine.

Any ideas?

Thanks
