Fast way to refresh args caller datasource

Cause I always forget these two lines of code to research the datasource of the calling args record in Dynamics AX. I will post it here so that I can google it every time I need it ;)


FormDataSource   callerDataSource;
;


if (_args != null
    && _args.record() != null)
{
    callerDataSource = _args.record().dataSource();
    callerDataSource.research(true);
}
