Hi Jiten,
A couple of questions to assist with finding the cause of your issue:
1) How are you changing the variable values? Through the standard variable prompt dialogue or through scripting with the new values obtained from a component such as a dropdown or input field?
2) If you add a listbox to your application and then place the following code in your "On Startup" event script, what exact variable names are listed?
var myVariables = DS_1.getVariables();
myVariables.forEach(function(element, index) {
LISTBOX_1.addItem(element.name,"");
});
3) Have you tried using APPLICATION.setVariableValue(variable, value) instead of APPLICATION.setVariableValueExt(variable, value) ?
4) Have your tried using DS_1.setVariableValue(variable, value) or DS_1.setVariableValueExt(variable, value) ?
Regards,
Mustafa.
