All features in the layer from feature service are invisible in the Flex Viewer

[OlegLukyanov]

I create feature service wirh 2 layers. But all features in the 1 layer are invisible. I can see feature's attributes only in attribute table.

I add new feature in this layer and I can see this feature in ArcMap, but not Flex Viewer.
I can see feature in this layer from feature service in Silverlight Viewer only when this feature is selected.

Any help please.

Thanks

Oleg,

What do you have your alpha value set at in the layer tag in the main config file?
