When loading a Feature Service from my localhost, I came to this strange thing: All my feature layers are loaded without any error, but they can not be seen on the map.
In ArcGIS, it should be like this:

In Browser, it shows nothing. However, click on feature do does a query and returns the right data.

Changing Layer's Display Order does not fix it.
Do I have to write a client js Render myself, or am I missing something. Can anyone give some help.
