Screencast: BPMN 2.0 import in the Activiti Designer
I mentioned in my last blogpost that the latest release of the Activiti Deisgner is feature-packed. Besides ‘diagram interchange’ support, the other major milestone is support for importing any BPMN 2.0 process.
In the following screencast, I demonstrate that this is no empty promise. Using a non-Activiti BPMN 2.0 editor (the open-source Yaoqiang editor in this case), a process is modeled and later imported and enhanced in the Activiti Designer.
Enjoy! Be sure to set the video to full screen to enjoy it to the fullest 
Howdy!
Nice screencast but did you notice (or was it just me?) that you have options for:
1) amount > 500
2) amount <=499
But what about amount == 500? Would you run it and let me know what 500 does?
@Eric: lol, my mistake! Let’s assume expenses of 500$ are neglected in this company
But it does prove you followed very closely! Thanks!
Actually just by accident that I watched this one, but that one jumped out at me… I am not used to you making calculation errors!
Maybe time to get you back into the field to freshen up them skills?
Ah well – my unit tests would’ve caught them very quickly, I’m sure
Very nice. The first example I have seen of direct import of bpmn 2.0 xml into a BPMS design tool. Oracle still cannot do it 9 months after launch.
Very useful screencast. Import of bpmn 2.0 xml makes it easy for developers to build a powerful BPM project.
Very nice one.
you got that talent to have a process working in a web application from scratch in a few minutes.
Well done, great tool
Hi,
I just tried to run your example exactly like you do but activiti always throws this error after clicking on “submit form”:
org.activiti.engine.ActivitiException: Form with formKey ‘/diagrams/request.form’ does not exist
at org.activiti.engine.impl.form.JuelFormEngine.getFormTemplateString(JuelFormEngine.java:63)
at org.activiti.engine.impl.form.JuelFormEngine.renderTaskForm(JuelFormEngine.java:47)
[...]
I checked whether the request.form-file is in the BAR-file by unzipping it. The file is in the BAR-file.
So everything should be correct – what am I doing wrong?
Regards,
Hendrik
is the bar file in the diagrams folder?
i have the same problem as Hendrik and i’ve stucked there for 2 days.

I’m not sure your expression had a correct syntax: expression should be of the form ${}, and it looks like you are using regular parantheses there …
Also make sure your amount variable actually exists.
