- library/nx/nx.tcl: Following the code review, implemented a first scheme for handling traces in setCheckedInstVar. This gives us consistent behavior for defaults and traces (valuechangedcmd) across classes and objects. - tests/parameters.test: Adjusted the relevant tests - Pending: setCheckedInstVar currently uses ::nsf::is to validate the value (e.g., default value) to be set. However, it might get passed parameter options which do not fit the NSF_DISALLOWED_ARG_VALUECHECKED filter.
