How to create the Dialog Lookup MultiSelect from BaseEnum?

Question

I need to add in my DialogField a MultiSelect Lookup. The values show aren't from record table (like Custom Account...), but they come from a BaseEnum.

I want to select more than one value from lookup:

For example, the user can choose at the same time Planned and Pais. My current code is this:

My class extends RunBaseBatch, in

public Object dialog()
{
    DialogRunbase dialog = super();
    ;
    dlgMultiSelect= dialog.addFieldValue(enumStr(SubledgerJournalEntryType),"","Select MULTIPLE VALUES","Select MULTIPLE VALUES");
    return dialog;
}

How can allow Multi Select lookup?

If it can not possible, there is other way for multiple lookup?

Thanks in advance

Feel free to use this test class for inspiration:

class StackOverflowTestDialog extends RunBase
{
    DialogRunbase           dlg;
    FormBuildStringControl  formBuildCtrl;

    SysLookupMultiSelectCtrl sysLookupMultiSelectCtrl;
}

static void main(Args _args)
{
    StackOverflowTestDialog testDialog = new StackOverflowTestDialog();

    if (testDialog.prompt())
    {
        testDialog.run();
    }
}

public Object dialog()
{
    DialogGroup         dlgGrp;
    FormBuildControl    grpCtrl;

    dlg     = super();
    dlgGrp  = dlg.addGroup();
    grpCtrl = dlg.formBuildDesign().control(dlgGrp.formBuildGroup().id());

    formBuildCtrl = grpCtrl.addControl(FormControlType::String, identifierstr(ctrlTypes));
    formBuildCtrl.label("@SYS329959");

    return dlg;

}

public void dialogPostRun(DialogRunbase _dialog)
{
    CFMEnumLookupTmp        lookupTmp;
    FormRun                 formRun;
    Query                   q;
    QueryRun                qr;
    QueryBuildDataSource    qbds;
    DictEnum                dictEnum;
    int                     i;

    super(dlg);

    formRun = _dialog.dialogForm().formRun();

    if (formRun)
    {
        //Fill in temporary table with enum values
        dictEnum = new DictEnum(enumNum(SubledgerJournalEntryType));
        for (i = 0; i < dictEnum.values(); i++)
        {
            lookupTmp.EnumValueLabelText = dictEnum.index2Label(i);
            lookupTmp.insert();
        }

        //Prepare a queryRun to work with the temporary table
        q = new Query();
        qbds = q.addDataSource(tableNum(CFMEnumLookupTmp));
        qbds.addSelectionField(fieldNum(CFMEnumLookupTmp, EnumValueLabelText));
        qr = new QueryRun(q);
        qr.setCursor(lookupTmp);        

        //Multi-select control framework class
        sysLookupMultiSelectCtrl = SysLookupMultiSelectCtrl::constructWithQueryRun(
            formRun,
            formRun.design().control(formBuildCtrl.id()),
            qr,
            true,
            [tableNum(CFMEnumLookupTmp), fieldNum(CFMEnumLookupTmp, EnumValueLabelText)]
    );
    }
}

public boolean getFromDialog()
{
    if (sysLookupMultiSelectCtrl)
    {
        info('Result: ' + con2Str(sysLookupMultiSelectCtrl.getSelectedFieldValues()));
    }

    return true;
}
