Behaviour of formula string\split

[esendino]

Hi

I was using this expression

$array = string\split($txtfield,',');

It split text by the comma as expected and provide as many items of the array as expected.

If the field $txtfield has some text without any comma gives an one single item array. Perfect.

But if $txtfield is null I would expect it provides an empty array with no item

Instead of that I receive an array with one item. And that item is null

Seems to me that this behaviour is not correct.

Not sure. I'd rather throw an error. It treats null as ''. I'm ok with it.

It's the same behavior as PHP has. It will throw error in the future.
