    When you first *createmark elems 'by config' bar2

    then don't mask it (mask &  reverse), because when you reverse mask, some other elems may be displayed

    just *createmark 'by config' bar2 and then update (*attributeupdate...)

    do not *createmark properties 'by displayed', instead, first *createmark elems 'by config' bar2

    then retrieve their properties by hm_getvalue and update those properties

    if you mark properties 'by displayed', some other properties may be selected and updated!
