Patrick,

This is a known issue, see:
   https://bugs.eclipse.org/bugs/show_bug.cgi?id=161605

Perhaps you could explain why you want to programmatically change a
specific option. A more common practice is to disable specific
options or enumeration values based on the value of other options.
E.g. you can have an enum with values unroll.1 and unroll.2 in which
unroll.2 is only enabled (visible) if a specific checkbox is selected.
