active(state) expression is not handled as boolean expression

[GoogleCodeExporter]

[active(<state>)] works great to allow a transition when I'm in a
particular state, however, [!active(<state>)] gives a syntax error. I
also tried [active(<state>) != true], but it didn't work either. Does
active(<state>) not return a boolean? It sure would be nice if it did.

What steps will reproduce the problem?
1. define a guard with !active(<state>) 

What is the expected output? What do you see instead?
it is expected that this is a valid expression but an error marker is set
