[Bug 1015] New: Scripting incorrectly processes complex conditional in while() statement

http://bugs.orocos.org/show_bug.cgi?id=1015

           Summary: Scripting incorrectly processes complex conditional in
                    while() statement
           Product: RTT
           Version: 1.10.3
          Platform: All
        OS/Version: GNU/Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Scripting

This works in a v1 Orocos RTT script (part of a .ops file):
{{{
       var bool timedOut = false;
       var bool finished = false;
       // a bug in RTT means that if you put the "finished" condition in the
       // "while" directly, it doesn't work. Using the variable does work.
       while !finished && !timedOut
       {
               do nothing;
               try logInfo(rt_string("Waiting ..."));
               set waited = waited + getPeriod();
               set timedOut = (waited > maxWait);
               set finished = RobotCommands.Sender.inFinalState() &&
                       RobotTelemetry.Sender.inFinalState() &&
                       !isRobotInitialized.Get();
       }
}}}

The following fails. It appears to just pick up the robotInitialized bit, and
not wait for the state machines ("Sender") in the two RobotXXX peer components.
I tried various orderings of the conditional parts.
{{{
       var bool timedOut = false;
       while !RobotCommands.Sender.inFinalState() &&
                       !RobotTelemetry.Sender.inFinalState() &&
                       isRobotInitialized.Get &&
                       !timedOut
       {
               do nothing;
               try logInfo(rt_string("Waiting ..."));
               set waited = waited + getPeriod();
               set timedOut = (waited > maxWait);
       }
}}}

We suspect that this is likely a bug in the v2 Orocos scripting also.
