26468	Bug in models.functions.ConcatPair for sqlite	jerch	nobody	"Concat is not working for me due to this line in models.functions.ConcatPair.coalesce:

Coalesce(expression, Value('')) for expression in c.get_source_expressions()

Coalesce(expression, Value('""""')) for expression in c.get_source_expressions()
}}}
