[incquery-dev] default string representation for null label features

["Ábel Hegedüs" <abel.hegedus@xxxxxxxxxx>]

Hi all!

In the current version, if you create a label (or databinding format string) like "$A.name$" and the value of name for the match parameter A is null, then the string representation will be "null".

While this does offer a distinction between null value and empty string, it creates another collision with the "null" string. When used in Viewers, it seems that using empty string for null values (or null strings at least) would be more convinient than the "null" value.

What do you think? I have added the question as a topic for the next meeting.

Cheers,
