Thanks for your request. There is an easy way to connect one input with two or more outputs: Just create one input (with no connected output) and then two outputs connected to the input. You will get a similar result as in the online demo for i-doit pro.
The other way (two inputs connected to one output) is currently not possible with i-doit pro. Can you give us a simple drawing which scenario in real life you would like to document? Maybe there is a workaround.
I figured it out. Our i-doit instance is set to require authentication from JSON-RPC calls, which are not included in the JS files in the module. I unchecked this option and it works. As this is a test environment this is fine for now, but I may need to hard-code authentication at a later date when we move into production.
For all those, who have this problem, I found out the solution for the V4.1.15-8-default:
1st: keep cool (it took me several coffees to calm down on this silly thing. If the value for timeout is 0, so the setting is off or the value is wrong. Why the heck, wasn't this catched by the program??)
2nd: Login on your webserver, go into the i-doit-folder in the apache-webfiles (f.e. SuSE: /srv/www/htdocs/i-doit/…)
3rd: find the globals.inc.php
4th: open it with your favourite text-editor
5th: find and copy the following line:
