Hi,

I cant find any reference to the namespace “ABB.Robotics.Controllers.FileSystemDomain” on the developer website.

Am I being blind?

I am having issues with getting the CopyDirectory to work.

Error message: “Operation is not valid due to the current state of the object.”

The stack trace,

Hi Peter,

I can see from the callstack that CopyDirectory() which is a synchronous method, internally calls the async version, Begin/EndCopyDirectory. Seems like it fails in a post procesing step after copy operation has completed.

Which is the source and destination path? Does the destination path exist?

If you are familiar with the IAsyncResult/Begin/End pattern you can try calling BeginCopyDirectory and EndCopyDirectory instead and see if that works better or gives a more understandable exception.

Or wait until the development team has tried to repro this next week.
