I would like to auto save my diagram,
so in order to know if there was a change I am listen to modelChangeEventListener
then I can do this
let txn = event.object;
if (txn != null)
time to save
But I get to here in cases that a lot of thing changes such as when I disable the diagram (I get that property point is changed)
how can I know that only operation on nodes and links were done?
