i guess you did it for clarity, but it should not be
necessary to pass config that is undefined...

i'd rather document them in the class and set them there
to undefined

one slight problem i see with that is that the user has no indication
that something is loading when clicking the button...

you can use the 'waitMsgTarget' of the API2Request to show a
'loading...' mask on the grid
