getChildAt(position) null pointer exception

[dslak]

If I try to change (in custom listView) TextView bg color using myListView.getChildAt(position) I get NullPointerException on position greater than 10.

Also position lower than 10 bg color is applied to all items + 10
IE: if the position in 3, the bg color is applied on items 3, 13, 23, 33, etc...
