Hi Luis,
This is a bug in the current test version - if a process is deleted or not imported that is referred to in another process, and if that other process is used in a product system, the product system builder just assumes that the links from this process exist, and when the product system graph is to be opened, a null pointer occurs when this non-existent process is opened.
We are currently fixing this!
Best wishes,

Thanks Andreas!

That was helpful, I've been cleaning all the files and connections my precesses called upon. After a week of struggling, miraculously it worked!

I am thinking one of those connections was created (or missing) because during the building of my project I used a lot of copy-paste from previous-levels already-existing processes, this because I am unable to create flows or processes into an specific folder. So when I told the product system to "Add connected processes" & "Connect with system processes" some of those must have short-circuited ;) .

I've stopped using copies of other processes as the base for new processes, nevertheless I still I can't find a way to create flows or processes dircetly into the desired folder. So my only resort is to use the wizard, create the flow/process in the main category and then copy-paste it into the right folder. Is there a way to indicate the program to create the items on a spectific folder?

Thanks again for your help and "mit freundlichen Grüßen"!
