~~NOTRANS~~ ~~Title: Client side Exception~~ Usually the error dialog shows the root cause of an exception as first Exception, because it was the first occured Exception, e.g. try { throw new Exception("Root"); } catch (Exception e) { try { throw new Exception("Middle", e); } catch (Exception ex) { throw new Exception("Top", ex) } } The error dialog would show ''%%Root%%'' as message. If you want to show ''%%Top%%'' as message, simply use ''%%ClientException%%''. The exception is a simple wrapper for another cause. If used, the last exception will be the first. In our example it would be ''%%Top%%''.
