The cell data mixed up

[mittay]

Hi,
I have problem in sample app (seems it's lib bug)
I just added logic to hide and show email column:
if(mTableView.isColumnVisible(3)){
mTableView.hideColumn(3);
} else {
mTableView.showColumn(3);
}
But after invoking hideColumn method and scrolling down I see emails data in Birthday column. More scrolling down/up fixes it.
The same issue with showColumn and scrolling down: I see birthday data in email column.
