"Unable to get property 'parents' of undefined or null reference". - Still exist

[bt209]

When adding the "-Collapse All" "+Expand All" buttons, their events generate a "Unable to get property 'parents' of undefined or null reference".
I found that adding the'$table' as a parameter to the two calls to '_collaptable' from the ".act-button-expand-all" and ".act-button-collapse-all" to the click events fixed it, which is identical to what the '".act-button-expand" was doing.
Previous: _collaptable($('.act-more', $(item)));
New: _collaptable($table, $('.act-more', $(item)));
