Empy cell break / multipage grid

The solution here provided doesn't work with the multipage grid patch, which comes with version 1.0.

obj.setProperty('data/value', function(i,j){return toValue[j](myData[i][j]);});

doesn't work, which I tried it in stead of

obj.setDataProperty('value', function(i,j){return toValue[j](myData[i][j]);});

Only the data on the first page is sorted correctly.
