+##### Exceptions #####
+
+For assist in the development, router can catch exceptions from symfony2 controller.
+Example:
+
+###### Conroller (Symfony2) ######
+
+    public function testExceptionAction()
+    {
+        throw new \Exception('Exception from testExceptionAction');
+    }
+
+###### ExtJS application ######
+
+    Ext.Direct.on('exception', function(e) {
+        Ext.Msg.show({
+            title: 'Exception!',
+            msg: e.message + ' ' + e.where,
+            buttons: Ext.Msg.OK,
+            icon: Ext.MessageBox.ERROR
+        });
+    });
+
+Result of calling testException method will be ejection exception:
+
+    [
+        {
+         "message":"exception 'Exception' with message 'Exception from testExceptionAction'",
+         "where":"in \/home\/gh\/dev\/symfony2sandbox\/vendor\/bundles\/Ext\/DirectBundle\/Controller\/ForTestingController.php: 81",

+         "ExtDirect_ForTesting",
+         "method":"testException"
+        }
+    ]
+
+ExtJS can display an error message or do something else.
+
+_Warning! This mode can use only in the develop. In production mode, exceptions are handled by symfony.
+By default response is HTTP code 500, with the message: Internal Server Error._
