I have a simple codes below to build a hierarchy tree from a JSON data file. Error appears in dhtmxtree_json.js file. Is there something I missed in my codes or a bug in dhtmlxtree_json extension?



Thanks,

JSON data , used in your case, missed “id” property for each item.
Expected JSON data

{
items: [
{
id:“some1”,
text: ‘Students’,
type: ‘cat’,
children: [
{
id:“some2”,
text: ‘Vinod’,
type: ‘st’
},
{
id:“some3”,
text: ‘Suman’,
type: ‘st’
},
{
id:“some4”,
text: ‘Deepak’,
type: ‘st’
}
]

}
]
}

Hi,

After I added the ID’s to the json data file per your suggestion, I got this error: "Error Type: DataStructure. Description: XML reffers to not existing parents"

Thanks,
