             Summary: jsf.js: error handling output improvement
                 Key: MYFACES-3902
                 URL: https://issues.apache.org/jira/browse/MYFACES-3902
             Project: MyFaces Core
          Issue Type: Bug
          Components: General
    Affects Versions: 2.2.3
         Environment: Snapshot code 2.2.3 from trunk + Icefaces 4/Primefaces 4 
Firefox >=18
            Reporter: Krashan Brahmanjara


Myfaces core do not show real javascipt errors.
In _Dom.js there is a catch block in rows 192-203.
Unofortunately I see two errors
- Icefaces js has exceptions without message and description a message is directly a 'e' object. So an error 'invalid property' is printed to console
- development mode is ignored by this catch block, in reverse order checking too because jsf.ajax.getProjectStage() is not initialized

Workaround - because development mode is recognized we can only show an alert
{quote}
        } catch (e) {
/*
            if(window.console && window.console.error) {
               //not sure if we
               //should use our standard
               //error mechanisms here
               //because in the head appendix
               //method only a console
               //error would be raised as well
                if (e.message) {
                  window.console.error(e.message);
                } else {
                    if (e.description) {
                      window.console.error(e.description);
                    } else {
                      window.console.error(e);
                    }
                }
            }
            if(jsf.ajax.getProjectStage() === "Development") {
*/
				if (e.message) {
				  alert("Error in evaluated javascript:"+ (e.message));
				} else {
					if (e.description) {
					  alert("Error in evaluated javascript:"+ (e.description));
					} else {
					  alert("Error in evaluated javascript:"+ (e));
					}
				}
/*
            }
*/
        } finally {
{quote}
