json data source
posted

Have very simple setting : 

<body>
<div id="auditSetCombo"></div>
<script type="text/javascript">
var uoaAuditSetUpController = function () {
function bindAuditSetCombo() {
var auditsDDwn = JSON.parse('[{"AuditId":0,"AuditName":"unassigned"},{"AuditId":1,"AuditName":"Audit_32513_1"},{"AuditId":2,"AuditName":"Audit_32513_2"},{"AuditId":3,"AuditName":"Audit_32513_3"}]');
$('#auditSetCombo').igCombo('option', 'dataSourceType', 'json');
$('#auditSetCombo').igCombo('option', 'dataSource', auditsDDwn);
$('#auditSetCombo').igCombo('dataBind');
}

return {
bindAuditSetCombo: bindAuditSetCombo
};
}();
$(function () {
$("#auditSetCombo").igCombo({
valueKey: "AuditId",
textKey: "AuditName"
});
uoaAuditSetUpController.bindAuditSetCombo();
});
</script>

</body>

when run getting the following error : 

Uncaught Error: There was an error parsing the JSON data and applying the defined data schema: Cannot read property 'Metadata' of null  infragistics.core.js:228

I am on 14.1 and if I would remove $('#auditSetCombo').igCombo('option', 'dataSourceType', 'json');  it would work fine... why it is not accepting 'json' type.. it works in similar circumstances in other places..

    Hello mcseidel,

    Thank you for posting in our community!

    I would like to inform you that igCombo was improved and rewritten in version 14.2 . This means that all other older versions are considered non-supported.

    I'm sending you sample with your configurations but with the latest combo version. As you can see there - no error is thrown.

    Also our IgniteUI product is already open source and the latest version of the source code (of almost all of the widgets) can be found here: https://github.com/IgniteUI/ignite-ui .
