[Gambas-user] Problem with array, zero object

[Jussi Lahtinen]

Using public variable shouldn't be an issue. I bet you use the variable
somewhere else, which makes it null, before the clearing.
Why are you clearing empty array anyway? Or is that just effect of
cutting/editing the code for us?
If you want that to be solved, we need to see more code.
