Connections between blocks get mixed up

[Jari Lietzen]

Hi!

I have written a c function block and the interfacing function following 
this tutorial: www-roc.inria.fr/scicos/ScicosCBlockTutorial.pdf The 
function listens to a tcp-port and receives an output channel and a 
value as a command and sets the block's output(s) accordingly. I can add 
the block and connect it to other blocks and this is all working fine. 
I'm using scicoslab-gtk 4.3-3, Xubuntu 9.04 with kernel 2.6.29.4 patched 
with RTAI. I'm also using Etherlab Scicos Toolbox as I'm using Scicos to 
generate standalone code for EtherCAT fieldbus components.

If I add my own block to Scicos diagram and connect it with EtherCAT 
blocks, everything is fine. Codegeneration works and the resulting 
userspace program does what it is supposed to do. However, if I change 
the connections originating from my own block, everything still looks 
good in the diagram, but in the generated code the connections between 
blocks are mixed up. Then changing connections back to their previous 
state doesn't correct the situation. Everything still looks good, but 
the connections are still mixed up. When I remove all connections from 
my own block and draw them again, only then the connections are really 
ok in the generated program.

I can send sample diagrams, screenshots etc. to illustrate the problem.

Best regards,
