Hello,
Tried Java Snippet Row Filter, and it looks like it has a bug. Run it on small table with 20 rows (made by Data Generator), configured it with exact expression, that it has in description:
return $$ROWINDEX$$ % 2 == 0; which is supposed to filter out every other row.
Resulting table has - oops - 11 rows.
A bit more poking around shows that it apparently doesn' t correctly process the 0th row.
Meanwhile the same functionality could be created by separate Java Snippet and Row Filter nodes.
WBR,
Kitsune
