Compare active tabs on both panels (help)

Help & Support
1

The following script, inspired by @aprold's (link), aims to compare the active tabs in both panels and select different files and folders. As it stands, the files are selected correctly, but the folders aren't. Could someone tell me the cause of this problem? Thank you very much.

function OnClick(clickData) {

    var srcItems = {}; // Unique items (files and folders) in the left panel
    var dstItems = {}; // Unique items (files and folders) in the right panel
    var commonItems = {}; // Common elements

    // 1. Get information about elements in the left panel
    var srcEnum = new Enumerator(clickData.func.sourcetab.files);
    while (!srcEnum.atEnd()) {
        var item = srcEnum.item();
        var key;

        if (item.is_dir) {
            // For folders: name and size
            key = item.name + "|" + item.size;
        } else {
            // For files: name, size and modification date
            key = item.name + "|" + item.size + "|" + item.modify;
        }
        srcItems[key] = item;
        srcEnum.moveNext();
    }

    // 2. Compare with items in the right panel
    var dstEnum = new Enumerator(clickData.func.desttab.files);
    while (!dstEnum.atEnd()) {
        var item = dstEnum.item();
        var key;

        if (item.is_dir) {
            // For folders: name and size
            key = item.name + "|" + item.size;
        } else {
            // For files: name, size and modification date
            key = item.name + "|" + item.size + "|" + item.modify;
        }

        if (key in srcItems) {
            // If element exists in both panels with the same attributes
            commonItems[key] = true;
            delete srcItems[key]; // We removed it from the only ones on the left panel
        } else {
            // The element is unique in the right panel
            dstItems[key] = item;
        }
        dstEnum.moveNext();
    }

    // 3. Select unique items in the left panel
    clickData.func.command.ClearFiles();
    for (var key in srcItems) {
        clickData.func.command.AddFile(srcItems[key]);
    }
    clickData.func.command.RunCommand("Select FROMSCRIPT DESELECTNOMATCH");

    // 4. Select unique items in the right panel
    clickData.func.command.SetSourceTab(clickData.func.desttab);
    clickData.func.command.ClearFiles();
    for (key in dstItems) {
        clickData.func.command.AddFile(dstItems[key]);
    }
    clickData.func.command.RunCommand("Select FROMSCRIPT DESELECTNOMATCH");

}

Use all instead of files in clickData.func.sourcetab.files. Same for desttab.

If I've understood what the script does correctly, I think you can also do it like this without scripting:

Select DESTTOSOURCE=notin DESELECTNOMATCH
Set SOURCE=Toggle
Select DESTTOSOURCE=notin DESELECTNOMATCH
Set SOURCE=Toggle

(This is the same thing the default Edit > Select Other > Select Source-not-in-Destination command runs, but it runs it in both directions instead of just one direction.)

I tried the code but I don't get the same results, but it was great to know this possibility, thanks.

@dasota's code finds items that are in both dual file displays that are different. @Leo's code would not find those items as they are in both dual file displays and thus not unique. A unique filter always has the possibility to be smaller than a difference filter.
