I am fiddling with JointJS, which uses the Backbone object model. I try to populate the cells with links and sometimes the links do not appear (after a few refreshes they appear again) with this error (in Chrome JS console) :
Uncaught TypeError: Cannot read property '_listenerId' of undefined joint.js:15417
That never appears with the states (simple rectangles from joint.shapes.basic.Rect).
My code for populating the link array is :
jQuery.fn.addedges = function (data) {
var links = new Array();
$.each(data, function (key, value) {
links.push( new joint.dia.Link({
source: { id: value.u },
target: { id: value.v },
attrs: { '.connection': { stroke: 'white' }, '.marker-target': { fill: 'yellow', d: 'M 10 0 L 0 5 L 10 10 z'} }
}));
});
graph.addCells(links);
};
And the JSON (converted into a JS object) :
[{"u":"ID_25","v":"ID_26","value":{"label":""}},{"u":"ID_25","v":"ID_27","value":{"label":""}},{"u":"ID_27","v":"ID_26","value":{"label":""}},{"u":"ID_29","v":"ID_26","value":{"label":""}},{"u":"ID_29","v":"ID_121","value":{"label":""}},{"u":"ID_223","v":"ID_121","value":{"label":""}}]
Do you have any idea of what could be the cause of this ? Is is a bug from Joint.js ?
Thanks ! Adrian
