The GraphLinksModel.linkFromPortIdProperty, if it’s a string, must name the property. It is not a property path. It cannot have a TypeScript type declaration in it. Presumably the property name is not something with a period and a colon in it – although that would be possible, it’s unusual and hard to type.
graphLinkModel has linkDataArray of type sequenceFlow
the separation of the data is a BMPN 2.0 standard (not mine)
I did not know that i can set GraphLinksModel.linkFromPortIdProperty to a function,
I will start working on that , that should be ok,
is there a sample for this?
