Why does the Results view show errors when I open a map in Oxygen DITA Map Editor?
You can ignore the errors for .ditamap files.
Symptom
When opening a map in the Oxygen DITA Map Editor, the Results view shows Error while parsing reference error messages.
Problem
The error messages are displayed for the DRM containerpart and for any submaps. This is because they are not synchronized to your workspace and cannot be located by the Oxygen editor.
Solution
For any containerparts or submaps, you can ignore the errors.
