I created a custom vertex with 4 ArrayLists as atributes. After saving the graph in an XML file, I remarked that the atributes are not wrote in the file. Is there a way to add them into the file when saving and showing their contents?

Using the java version of JGraphX.

Thank you for help.

Did you register your custom object properly? See my answer here for an example: http://forum.jgraph.com/questions/4850/ioexception-when-trying-native-java-serialization

Thanks Lofi, but my custom vertex is inheriting from mxCell. And when I load the graph all cells are there except the custom one not visible. I added the registerCodecs() to my code when saving but it didn't work too.

You shouldn't inherit from mxCell. Instead you should make a custom object, e. g.:

public class MyObject implements Serializable {

private String name;

private List<string> list;

public MyObject() {


public String getName() { return name; }

public void setName(String name) { this.name = name; }

public List<string> getList() { return list; }

public void setList(List<string> list) { this.list = list; }


and use it as the cell's value.
