Instance Scan checks List Layout with more than one List Element on the same position

[aditi__patil]

I am trying to make an instance scan check such that it checks lists with more than one element at same position from sys_ui_list_element table.

I have made a table check with the following script but am unable to get the correct findings. Please review

(function(finding) {

    var gr = new GlideRecord('sys_ui_list_element');

finding.setCurrentSource(gr);

    gr.query();

    var listIdMap = {};

    while (gr.next()) {

        var listId = gr.getValue('list_id');

        var position = gr.getValue('position');

        if (!listIdMap[listId]) {

            listIdMap[listId] = [];

        }

        listIdMap[listId].push(position);

    }

    for (var listId in listIdMap) {

        var positions = listIdMap[listId];

        var positionCount = {};

        var hasDuplicates = false;

        for (var i = 0; i < positions.length; i++) {

            if (positionCount[positions[i]]) {

                positionCount[positions[i]]++;

                hasDuplicates = true;

            } else {

                positionCount[positions[i]] = 1;

            }

        }

        if (hasDuplicates) {

            finding.increment();

        }

    }

})(finding);
