local indexes reload

In the atached project & snapshot :

- select 2-nd row of the grid

- select the shown record in the list box

- move to the last record of the grid, it clears seletion in the listbox

- return again onto 2-nd row of the grid, it will revert the value of listbox

The wanted behaviour to clear "dmmainmo.qryChoice('index_code')" as soon as moving in the grid cause the bound paramlink to clear "dmmaimo.qryIndexList", not autoamtically by the event handler dmmaimo.qryIndexList.AfterRefresh.
