3962	OMEdit variable overrides	crupp@…	Adeel Asghar	"At some time in the last year, OMEdit switched from using -override to set changed simulation parameters to updating the parameters in the init.xml file directly. I don't like this change because the original set of start parameters are lost once an updated simulation is run. It is then no longer possible to use the original set as a reference point and it is also possible to mess up your start values such that the model no longer works (e.g., for initialization), thereby forcing the user to rebuild just to get a new init.xml file.

My preference is to use the init.xml file as a reference file and then use the -override command line option to update parameter start values. This lets the user, for example, easily do parameter sweeps of one variable at a time without worrying about resetting old variables to their original values.

Is there any way to revert back to the old behavior?

Maybe there are good reasons for this change that I am unaware of?

Perhaps giving OMEdit the option to reset parameters to the original values defined in the init.xml file would be a nice feature?"	enhancement	new	normal	Future	OMEdit
