displaying triplet in 3/4 time

[Ole Schmidt]

Hi,

While engraving I came across the  problem to display a simple triplet which 
consists of a quarter and an eighth note
and it seems to be difficult. The default beaming is odd and using brackets 
leads to an error warning.
Do I completely miss something or is it a known problem?
thanks for a hint
