"NoDataValue" in Variables table is reset

xenomorph1030[CodePlex]
I migrated the data I had from SQL Server to MySQL. While I was playing with HSL, I checked what management features were available and ran through all of the quotchangequot forms by hitting save. It reset the quotNoDatavaluequot in the variables
table to -9999 which was incorrect in my case. The data plot sure was interesting afterwards. I simply changed it back manually in the database.

Reproduce the problem by opening the management change forms and saving the affected variable, then inspect how the Variables table persists NoDataValue. Done means saving those forms no longer resets an existing NoDataValue to -9999; verify the value remains correct after the save.
