Here the problem is that 'add' splits the value first by calling Perl's
split(/\n/, $value), and then pushes the resulting list of values into the
context event buffer. Unfortunately, when all value fields are empty, a list
with size 0 is produced, and nothing get pushed into the context event store.
The issue of adding a newline to context event buffer is slightly tricky.
Actually, you can never add a newline as such, because it acts as a delimiter
and can thus never end up in event buffer. Therefore, the task could be better
worded as adding an empty string (or whitespace) to the event buffer. It is
obvious how to add a whitespace string (just assign " " to %N), but handling
empty string(s) with split() is not that obvious (I have tried to rewrite /\n/
partitioning regular expression in several ways and play with these versions,
but currently have no clue what's the best solution).
kind regards,
