this is a patch to avoid problem of "issue 3 'ondemandselect' option".

About "MCSParameters=ondemand,noselect:groupA|groupB|groupC",
you can separate ondemand,noselect and groupA|groupB|groupC into 2
parameters like you want. The first part is common for mcs plugin and
the second part is only for mcs/group, so it could be logical to put them
into 2 different parameters.
