Datagrid as component in form component - filter submit bug

[BigOHenry]

I have a form component and inside that i am creating datagrid component. When i want to submit a form or add container with button to WebChemistry/Multiplier (its a replicator) the filter is submitted even there is no filter... After filter submit any form operation is skipped (data save, my snippets refresh, etc.)

$grid = new DataGrid();
        $this->addComponent($grid, $name);
        $grid->setStrictSessionFilterValues(false);
        $grid->setPagination(false);
        $grid->setRememberState(false);
        $grid->setAutoSubmit(false);

Any idea what to do with this bug? Or am i doing something wrong?

So basically you have nested forms because the datagrid itself is a form. Not sure if this behavior is indeed supported. Even HTML5 itself does not support this feature.

From top of my head, you could modify the datagrid template (you do not use filters anyway) in which you would remove the wrapping form of the datagrid.. not sure thou how that would turn out

[radekdostal]

public static function removeFormElementsFromDatagrid(string $html): string
{
  return \Nette\Utils\Strings::replace($html, [
    '/<form\s+.*>+/' => '',
    '/<input type="hidden"\s+.*-->/' => '',
    '/<\/form>/' => ''
  ], NULL, 1);
}

{capture $grid}
  {control grid}
{/capture}
{$grid|removeFormElementsFromDatagrid|noescape}
