I need an explanation of how Data Input Objects should work in JBPM. If data input is not available should it block the task? So from this explanation I concluded that if I have a human task which has an association to a data input object, the task should not start until this object is available? I've tried a little example, with a simple process shown below but the human task gets activated and I only get a warning message  "Could not find variable scope for variable DataInput_1 when trying to execute Work Item Human Task. Continuing without setting parameter." https://community.jboss.org/servlet/JiveServlet/downloadImage/2-803763-20... (https://community.jboss.org/servlet/JiveServlet/showImage/2-803763-20470/...) What I want to achieve is that human task is activated when I insert the required data input to ksession (e.g. some data gets submitted to a system and I pass it to ksession so human task can be executed). How do I have to model the process to achieve this blocking behaviour? Thanks! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/803763#803763] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
