Not successful in updating myVersion in which I present a problem Not successful in updating myVersion using ArcObjects (as a feature is Inserted into myVersion, this feature is also inserted in other versions too). Then, I tested a editing on ArcMap. A SDE versioned layer is loaded on ArcMap session. However, when I Start Editing, I got warning: No Editable Layers.
I searched around for "No editable layers" but could not find the proper solution. I appreciate if you can share your experience.
