Description

When using the same basic item name for more than one job in different folders, and those items are used in a pipeline, the view is not displayed (Error communicating to server! Server Error)

The stacktrace shows an NPE:

Caused by: java.lang.NullPointerException

The reason is that ProjectUtil.getAllDownstreamProjects() stores the projects in a map using the simple name as a key. So of all equally named projects only one is retained, so the firstProject is usually not found as vertex in the graph leading to the NPE.

I will create a Pull Request for that.
