I am currently working on ArcGIS 10.1 SP1, every once in a while, when I am editing and click "save edits" the attributes for the last point that I had created disappears. The point itself is still visible but to get the attribute table back to normal I have to close and reopen ArcMap.
I have noticed that after point creation, the FID will not be sequential. The problem will occur the next time that I save my edits.
Hope to hear from you soon. Thanks.
Personal Geodatabase or SDE or Shapefiles.
Are you features Joined to another feature or a table? If so that could be causing issues. If in a Geodatabase, or SDE have you compressed it lately?
For the FID compressing your database may take care of that. Especially in SDE. When you create and or delete features it creates a delta table where the edit is saved. You cannot see it but it is there. and it will consider the FID as being used. when you compress your system it should free that up.
