Reading ArcGIS Online Feature Service shared with the organization - not owned by the user or shared with a group.

I am dealing with this same issue. If someone knows how to connect to shared Feature Classes in ArcGIS Online owned by others, i'd like to see the solution.

Follow these steps:

• Use a FeatureReader
• Load up a featureservice that you have access to (e.g. via group or user) and ok in featurereader
• Now, go back into the featurereader and into parameters
• Get the item id from the layer you actually want to read and update the item id in the reader:

• 

  Then ok through the screens.The featurereader should update, providing you with the name an feature layers and there schemas, and will read the data.
