Description

TableTree#updateNode() tries to locate the corresponding node by visiting all Item children. If this node is not visible currently (e.g. because a parental node is collapsed), the children visitor runs into the table header (which comes after the table body) - causing a ClassCastException when the Item is expected to have a NodeModel, which it doesn't inside the header (or footer).
