Re: [wsbpel] Issue 27 - Proposal to vote - Setting link status incase of transitioncondition

[Prasad Yendluri <pyendluri@webmethods.com>]

True. This aspect was clarified in the discussions related to this issue but did not make into the
proposed resolution (we voted on!).

I also see the need to address what the status of the link ends up being in this scenario. The
obvious answer seems to that "a transition condition evaluation error would be same as the
transition condition having evaluated to 'not ture'/false'." But, I somehow feel some will not
see it this way. In any case we need to make a definitive statement here and not leave a
loose end dangling.

Also from the discussion on issue 27 I get that the local variables of the scope 
cannot be used to evaluate the transition condition of the links and only the 
variables of the parent scope should be used. This needs to be documented 
explicitly as well.
