Layer is not editable Error

[Craig_Eissler_Iceman]

Hello,

I am getting the Layer is not Editable error message when attempting to create a simple GDB feature class feature (see below for one example):

Sometimes that is not indicated at all in the List by Editing view... Q1: why not?

Sometimes it is, but only a Warning. I understand the Warning message (different coordinate systems causes projection on the fly), but the Status dialog states that it is still editable... Q2: what's going on? ...Q3: In addition, how can something be both an Error and a Warning?

Thanks,

Craig, that layer looks different from what I would expect to see. Can you share the properties of that layer as a screenshot here? I would be looking for the Source tab and then the feature types/geometry types and what not:

Thanks, but my question is really more about how ArcGIS is reporting these Warnings/Errors ,and the apparent inconsistency.
