I have to use activiti modeler. but there're still too many problems. oxy compressor build failed , even i add utf-8. I have to remove compressor to fix it, but after deployed, the flow editor is blank.
There's a nice book about Activiti (see link below) 😉 But the user guide should provide a lot of information as well. Please tell us more about the issues you run into so we can provide help for that.
