Hello,

I am trying to create my own CNF content and it works so far, but I don't get it working, that a empty project doesn't get the "child" symbol.

In my hasChildren method I return false to test the system.

Thanks for any advices.

It seems that the parent ContentProvider always returns true.
Is the only solution to create a own ContentProvider for all resources?

The class org.eclipse.ui.internal.navigator.resources.workbench.ResourceExtensionContentProvider is responsible for the "incorrect" input.
Extending isn't possible, because it is an internal class. You can extend the WorkbenchContentProvider, but there are a lots of stuff missing like the automatic refresh of the navigator or the correct sorting, that means the folders are listed with the files and not seperated at the top of the list.
