ListGrid RestDataSource and Errors : errorMessage

[immobilia]

Hy, i follow the RestDataSource on ShowCase and the RestDataSource javadoc

But, how to set an alert ? when :
* An unrecoverable error, such as an unexpected server failure : status = -1
* Validation failure : status = -4

By default, the listGrid and DataSource does not create alert when error occur ? What's the best way to catch and displays errors (errorMessage) ?

1) Register a global RPCManager error callback
2) Override transformResponse(..) of your RestDataSource and call DSResponse.getStatus().
Edit : You can also register DataSource.addHandleErrorHandler

Validation failure : status = -4

It's damage we can not use the same fonctionnality of Validator on Update RestDataSource.

In a Remove RestDataSource, as you say, i add a HandleErrorHandler and get errors with event.getResponse().getErrors().

But I do not know how to convert to Java Object instead of JavaScriptObject....
How to get all <response><data><record><errors> ? or convert response().getErrors() ?

        countryDS.addHandleErrorHandler(new HandleErrorHandler() {

			@Override
			public void onHandleError(ErrorEvent event) {
				SC.say("Error");
				
				Map erreurs = event.getResponse().getErrors();
				if( erreurs != null ) {
					System.out.println("response.getErrors() IS NOT NULL");
					Set<String> keys = erreurs.keySet();
					
					Iterator<String> it = keys.iterator();
					while (it.hasNext()) // tant que j'ai un element String non parcouru
					{
					  String s = it.next();
					  System.out.println(s + " : " + erreurs.get(s).getClass());
					  
					  JavaScriptObject javaScriptObject = JavaScriptObject.createObject();
					  javaScriptObject = (JavaScriptObject)erreurs.get(s);
					  
//					  Object o = JSOHelper.convertToJavaRefDataClassArray(javaScriptObject);
//					  Object o[] = JSOHelper.convertToJavaObjectArray(javaScriptObject);erreurs.get(s));
					  
					}
				}else{
					System.out.println("response.getErrors() IS NULL");
				}				
				
			}
			

        	
        });

<response>
	<status>-4</status>
	<data>
		<record>

			<errors>
				<countryCode>
					<errorMessage>errorMessage1</errorMessage>
					<errorMessage>errorMessage2</errorMessage>
				</countryCode>
				<capital>
					<errorMessage>errorMessage3</errorMessage>
					<errorMessage>errorMessage4</errorMessage>
				</capital>
			</errors>

		</record>
	</data>
</response>

Wrong format for validation errors, see the RestDataSource docs for the correct format to use for both validation errors and unrecoverable errors.

Yes, but the following RestDataSource exemple doesn't write my ListGrid fields as error.

 <response>
    <status>-4</status>
    <errors>
				<countryCode>
					<errorMessage>errorMessage1</errorMessage>
					<errorMessage>errorMessage2</errorMessage>
				</countryCode>
				<capital>
					<errorMessage>errorMessage3</errorMessage>
					<errorMessage>errorMessage4</errorMessage>
				</capital>
    </errors>
 </response>

Tomorow i'll check my XPath configuration.
