Nullpointer exception in TreeGrid.isExpanded(M model)

[ionut.rachita]

TreeGrid.isExpanded(M model) is not protected from NullPointerException if it is called with a model that doesn't exists in the grid.

public boolean isExpanded(M model) {
    TreeNode node = findNode(model);
    return node.isExpanded();
  }

If node is null then we have an exception.
