Description

For GroovyTemplates its not very desirable to have alot of "null" printed everywhere we might have included a possible null value. So it would be nice to have a way to make GString print "" instead of null.

Velocity does that via $!

{text}

which I think is ok, but we may just parse the Template text and always "insert" $

{(text == null) ? "" : text"}

since I think its always the desired behaviour for gstrings to not print null (within Templates).
