Unable to set the Downtime Cause Location to empty or null

[JoePlant]

When writing to the Ampla Data Webservice, if the Cause Location is null or string.Empty then web-service will throw the following fault.

The consequence of this exception is that the Downtime Cause Location field is not able to be reset. It can only be set to another Cause Location.

If using Production Analyst, then the Cause Location can be set to "(blank)" or "Reset" using the context menu.

Ampla Version: 5.2.6135

@alexmg, I am not sure if this issue has been fixed in later versions of the SubmitData. This will cause an issue for both Add and Update operations.

@JoePlant I'll email this to myself at the office and take a look.

Thanks @alexmg, I have added a feature into the codebase where it will not submit a Cause Location that is empty or null.
