still problem with datagrid v6.9.4
fix:
$values = $button->getParent()->getUnsafeValues(null);

Still problem in next branch. @tonyp90 Do you know, what does cause the problem? Some changes in nette/forms?

[tonyp90]

There was some changes between forms 3.0 and 3.1 which caused more problems than just this.

[radimvaculik]

Which another problems do you mention?
