}And after a calling of graph.fromJSON I see the nodes only (without link). I found that after graph.fromJSON all models have new ids. So I assume the links aren't shown cause they wrong ids (old). Could help me find the solution and load the graph from JSON? Thank you |

I think I have seen this before. There is nothing wrong with the When you create a custom shape by extending a class and you override the class Shape extends dia.Element {
initialize(...args) {
super(...args);
/* your code */
}
}Is it the case? |

I think I have seen this before. There is nothing wrong with the
JSONor thefromJSON()graph method.When you create a custom shape by extending a class and you override the
initializemethod (or similar) make sure to pass all the arguments tosuper.Is it the case?
