Sometimes there is a need to refresh the calling form’s data source(s) after the operation. For this reason task on the form could be used.
It is just calling the task which stands behind pressing F5 button on the form. There is a macro definition #taskF5 in macro library #Task. This could be done like in example below:
protected void refreshDataSource(Args _args)
if (_args && _args.dataset() && _args.record().isFormDataSource())
dataSource = _args.record().dataSource();
The example given above is applicable only if there is a single root data source on the refreshed form.
