in reply to Odd workings of split

From "perldoc -f split":
Note that splitting an EXPR that evaluates to the empty string always returns the empty list.
So it's not split that returns an undef, but the first element of the empty list that split returns (which is what you want to use) is undef.

I guess if you want to pass on an empty string (as opposed to undef) in such cases you would have to add a clause such as

$cmd[$_] //= "";

[ambrus]: No, you're not doing anything wrong. It's just that our automatic spam filters confuse you with the spammers who post advertisments for online shops of counterfeit branded clothing.
[ambrus]: Or unless you left the title field empty or entered a very short title for the node, but then you'd get a message saying that.
[ambrus]: I hope Corion or some other admin is here and can check the logs to see what the problem is.
[mz2255]: I wish I had an online shop but sadly no. The title field definitly wasn't short, had a perl module in the title with 5-6 additional words.
[ambrus]: you can also try to just post again in case it was some intermittent error
