Use of '\n' for line feed in Error strings

Since visualForce doesn't have good  error handling for custom controllers, I am  writing some custom code show error messages.

My custom controller is editing a table.

In the code below, I am a trying to insert a line feed after every error using '\n'. 

However,  when error messages are output, there are no separate lines - it is one big error message. i have tried '\r' as well - doesn't work.

Any thoughts.

Code:
       } catch (DmlException e) {
                     for (Integer i = 0; i < e.getNumDml(); i++) {
          string[] fields = e.getDmlFields(i);
          //strip __c
          string field = fields[0].subString(0,fields[0].length()-3);
          integer row = e.getDmlIndex(i); 
          String rowError =  'Row:' + (row+1) + ' Field:' + field + ':' + e.getDMLMessage(i);
          if (ErrorString[0] <> null) {
             ErrorString = ErrorString + '\n' + rowError;
          } else {
             ErrorString = 'ERROR:' + rowError + '\n';
          }
         }
