Given a mission with a description.ext that uses the array form of enableDebugConsole, bringing up a Zeus attributes dialog will show an error message dialog saying "'enableDebugConsole/' is not a value", requiring the player to dismiss the dialog. The report file will also show the following message
Warning Message: 'enableDebugConsole/' is not a value
Run the attached mission
Dismissing the error dialog allows normal use of the attribute editor dialog. The dialog and message are created only the first time an attribute dialog is brought up by Zeus. Apparently some sort of initialization code is expecting only the numeric forms of enableDebugConsole. The numeric forms do not produce an error.
This error is probably related to the 'Execute' box in which you can execute code.
When using enableDebugConsole[], the error appears and the 'Execute' box is gone.
Using enableDebugConsole numerical, the 'Execute' box is present with no errors.
