I've coded a report that does some operations and after the operations gives message to inform the user. If the operation is done successfully a message is displayed typed 'S' otherwise typed 'E' . The report has a button that displays log to inform user about the results of the operation. To display log I used 'Leave to list-processing' . When message's type is 'E', it displays log after the button has clicked. But when message's type is 'S', nothing is happened. I don't understand what the problem is.
