Return value from scxml executable block is not working

[joshythomas]

Hi Johan,

For returning a return value from scxml executable section,

I have been using queue as per your suggestions on issue#60

    <transition event="add_item">
        <script>
            queue.put(_event.data);
        </script>
    </transition>

</state>

q = Queue.Queue() sm.send("set_queue", q) my_item = q.get() # will return the above passed item

It was working fine till pyscxml-0.8_20111128_full-py2.7 and all later releases gives following error

Traceback (most recent call last): File "C:\Python27\lib\site-packages\eventlet-0.12.1-py2.7.egg\eventlet\queue.py", line 107, in switch self.greenlet.switch(value) error: cannot switch to a different thread

Please help me in resolving this issue

Regards, Abel
