Dear Knimers,

When ungrouping a row containing a Collection with 3 elements, I get 3 rows.

When ungrouping a row containing a Collection with 2 elements, I get 2 rows.

When ungrouping a row containing a Collection with 1 element, I get 1 row.

When ungrouping a row containing a Collection with 0 elements, I get… 1 row, with a missing value.

In some situations this is inconsistent behaviour. Yes I could remove the missing value row with a Row Filter or a Missing Value node, but then what about non-empty collections containing missing value elements? Therefore I suggest adding an option to the “Ungroup” node to remove rows with empty collections.

Best,

Aswin
