I'm trying to start with Activiti BPM system. For this task i bought book - "Activiti in Action" by Tijs Rademakers. In section 3.2 there are some samples of creating BPMN process in Modeler and importing created process into Designer. Everything ok, but when i'm trying to open imported process in Designer - i don't see any graphical objects of the process! Then i tried to import process from book samples project - and i see such problems. Is here anyone who catched problem like this and solved it?
After reading this forum, i see some strange things. It looks like Modeler by Signavio is not supported at this time. Maybe it's the core problem of task that i'm trying to do. Maybe there are some other solutions or open-source products for building BPM schemes, except Activiti Designer (Eclipse plugin)?
Answering to myself: I've got answer on stackoverflow website. Open your bpmn file with txt editor and manually change attribute isExecutable value to "true" inside process tag process id="sid-2b39da09-bebd-4ec2-a58e-be045cd15c55" isExecutable="true"
