Hi,

it was my mistake. first time as i run the explorer, i did generate the activiti database from the sql scripts file ( i totaly forgot about it).   and the error was trying to run the explorer with the demos configured in the spring context .

after creating new empty database and restart tomcat works fine.

best regards
younes

The 5.11.1 really doesn't work - try copying "Add sales opportunity.bpmn20.xml" (Activiti in Action chp.7), change to"Add sales opportunity.bpmn" and …. the designer shows empty screen. No any BPMN elements at all. Are there any workarounds for his?

I've just downgraded to designer 5.9.3

(using Eclipse Indigo Service Release 2)

Hi,

The problem is that the old Activiti Modeler automatically adds isExecutable="false" to the process element.
If you change false into true, it's opening fine. I'll try and fix this issue, because the Designer should of course also open definitions with isExecutable="false"

Best regards,
