Dear all,

I'm trying to get some data back from a protocol function call into the callback function.

Basically, I call a protocol function on click on an image, the protocol perform some computation which I'd like to get the result (single value) back into the javascript called back function for further display.

I'm either not sending properly the data back from the computation protocol, or not reading properly the results in java script.

Would anyone have a demo protocol on this topic?

PS:

• if you start from the joined protocol, save it in your protocols, run it, click on "1" and make it display the computation in the alert... it's all I need.
• I only need solutions using javascript a callback function.

Thanks,

Pierre
