Error Uncaught TypeError: Cannot read property 'children' of undefined about orgchart

Hi, fvlima, you tried the example -- ondemand-loading-data and got this bug ?

[fvlima]

I'm using the ajax datasource example. And I guess that is the point because theren't no more parents for a determined node, and the arrow is showed to perform a click to load more data. See my code:

$('#id).orgchart({ 'data': '../url/' + id, 'nodeRelationship': 'level', 'nodeTitle': 'relationship', 'nodeChildren': 'parents', 'nodeContent': 'identification', 'parentNodeSymbol': '', 'nodeID': 'id', 'depth': 4, 'createNode': function ($node, data) { if (data['img'] != undefined) { var miniature = $('<i>', { 'class': 'fa fa-info-circle second-menu-icon', click: function () { $(this).siblings('.second-menu').toggle(); } }); var img = '<div class="second-menu">' + '<img class="avatar" src="/media/' + data['img'] + '"></div>'; $node.append(miniature).append(img); } } });

I know that the error refers to opts.ajaxURL, because it doesn't defined, but I chose to not load data on demand, only a initial ajax request that brings me all nodes showing only the first four nodes.

Hi, fvlima. Does your returned json datasource contain corrent property "level", it's value should be "110" or "111". The three numbers indicate that whether the node has parent node, sibling node or child node.

You know, wrong indicator numbers will result in wrong arrows, and wrong arrows will mislead users to load non-existing nodes.

Hi. I need to ask apologies for my mistake. I thought that if a node had no children, then the orgchart would ignore automatically these empty children nodes. Maybe it can be developed to prevent situations like mine, because were not defined urls to load data on demand.

[dabeng]

Hi, fvlima, I got your point, I admit that in most cases, the indicator number is unnecessary except ondemand loading scenario, because in this scenario, orgchart needs some signal to load unknown nodes and in other scenarios, orgchart loads all nodes all at once, orgchart should be capable of generate the right collapsing/expanding arrows according the fixed hierarchy. I'll refine the code as soon as possible.

[dabeng]

The idea -- I thought that if a node had no children, then the orgchart would ignore automatically these empty children nodes, has come true in version 0.9.9.7 of orgchart.
