Filter LOV with LaunchPopupListener method?

Question

Hi!
I create a viewObject (read-Only QUERY) and for use it as LOV, I defined in his xml file: viewCriteria and bind variable.
In the other ViewObject added in three attribute LOV´s using as List Data Source the same viewObject i create before.
In view Accessor selected the view Criteria to apply and didnt define bind variable value bc i must asign diferent values for each attributes..so.. for each inputListofValue i difined in LaunchPopupLister method´s to set bind variable in view criteria.. and in this way show for each Attribute LOV filtered showing correct data.
How can i modify bind variable in backing for filter lov table?

Answer 1

I want to use a single ViewObject for Show Multiple LOVs. This ViewObject have three columns : TableName | Code | Description and i define view criteria TableName = :v_nomtabla.
At runtime as example when user click on CITY inputListofValue the popup LOV must show only Code | Descriptor where TableName = 'CITY'
I try to set v_nomtabla Variable before Display the LOV Popup using LaunchPopupListener
public void test(LaunchPopupEvent launchPopupEvent) {
getBindings().getOperationBinding("modificar").execute();
In ViewObj implementation:
public void modificar(){
setNamedWhereClauseParam("v_nomtabla","CITY");
executeQuery();
but dont work!.. the table in LOV dont show values.. and compiler dont throw errors..
