#1: arrows with anchors in the middle

hello,

Ich want to combine two normally separated state charts. 

a sample

chart1: an article, part of an order
state 1000 (article exists/activated)
state 2000 article planned
simple state chart
state 1000 --> state 2000

chart 2: an order
state 1000 (order exists/activated)
state 2000 (order planned)
"simple" state chart
state 1000 ---> state 2000 [only when all parts of th e order are planned]

for that I'd like to combine the charts
--> drawing an arrow between the both Arrows (combining by a condition e.g. all /at least one)
if all articles are planned, the order is planned

----------------------------------------------------------
I solved that in using and extending the sample
"ternary connection" 
that is not perfect because of that "dummy nodes"/auxiliary nodes
-------------------------------------------
a better solution would be Arrows with anchors in the middle and adding methods for chart analysis

------------------------
#2: second class layout
another problem, what exists while using
auxiliary nodes:
the automatic layout makes normally a good job;
but in such coupled charts the auxiliary nodes mind.

yes, i can switch them off from layouting;
but then they still mind.

what is needed? a after-layout-routing-routine for placing that nodes in a smooth way to their origin and destination
(better way: coupled arrows, no auxiliary nodes)

thanks,

Mathias
