Hi!

When there is a subgrid(s) expanded, getDataIds return an extra array element with an empty value in the place(s), where that subgrid(s) is.

I do not know, if it's a sufficiently advanced bug, which is indistinguishable from a feature, however from my project aspect I had to suffer a bit to finally find out, why the renumbering of rows sometimes does not work properly 😉

But keep up a great work!
