Data Source Editor - Cannot deselect output parameter

[allen]

via Stephen Bau:

I tried to add a data source output parameter, but this resulted in a Symphony Recoverable Error on the front end:

Argument 1 passed to fieldLink::getParameterOutputValue() must be an array, null given, called in /Users/stephen/Sites/sym3/piano-sonata/extensions/ds_sections/lib/class.datasource.php on line 887 and defined An error occurred in /Users/stephen/Sites/sym3/piano-sonata/extensions/field_link/fields/field.link.php around line 695

The output parameter that caused the error was a Link field.

Then, I was unable to deselect the output option. I could select another output option instead and save the data source, but I could not deselect all parameter output options. That is when I deselected the option and pressed the Save Changes button, the option was still selected after saving.
