How to save position of each node in swim lane grp

i have an bpmn editor along with swimlanes how can i save and retrieve the diagram along with node positions

Doesn’t the extensions/bpmn.html editor already support saving and loading models?

No its not saving the position of each node inside swimlane and whole diagram position

Those aren’t swimlanes (pools) exactly… they are what <span =“il” style=“color: rgb34, 34, 34; font-family: arial, sans-serif; font-size: 13px; line-height: normal; : rgb255, 255, 255;”>BPMN calls blackbox pools. Nothing goes inside them, they are just for connecting messaging from external nodes (i.e. messaging to/from an external process.)

Our swimlane sample only allows 1 pool, so it wasn’t sufficient for BPMN.

Adding this is on our to-do list.
