Hello, so im building an application in which i store some graph data in a database and then extract them using the GraphMLIOhanldler to read from an input stream into a Graph2D object and using getRealizer to return the NodeRealizer from the Graph2D. the problem comes when i try to feed this realizer to a Jlist in order to display it in a custom editor, all i get is what shown in the image, and its unusable if i write the stream to a file it works and i can see it with yEd but it doesnt work to be usable again in my custom editor, i dont know what im doing wrong to be honest and im not that experienced with java, so any help would be appreciatted with this problem, thank you!
