Boundary node linked with an inner node

Hi again,

I would like to extend my activity diagram by surrounding it with a boundary group displayed with a dashed line stroke. Furthermore, boundary nodes should be able to be linked with an inner node. I tried to implement the logic above by using some of the principles in the BPMN editor template (itemArray, itemTemplate) but it is kind of restricting mainly for two reasons:

  • Ideally the boundary nodes should be draggable across the boundary group.
  • Linking the mail icon with an inner node is not properly displayed (the source of the link should be the icon and not the bottom of the boundary group)
Any suggestions on how to deal with these issues? The scenario is shown in this jsfiddle. Thanks in advance!

We’re working on improving the BPMN sample in version 1.5. We’ll look into these issues next week.
