Response Packet Criteria

+ *

A response packet may contain: + *

+ *

JSON Packets

+ *

By default, response packets are assumed to be JSON, so a typical response + * packet may look like this:


+{
+    success: false,
+    errors: {
+        clientCode: "Client not found",
+        portOfLoading: "This field must not be null"
+    }
+}
+ *

Other data may be placed into the response for processing by the {@link Ext.form.BasicForm}'s callback + * or event handler methods. The object decoded from this JSON is available in the + * {@link Ext.form.Action#result result} property.

+ *

Alternatively, if an {@link #errorReader} is specified as an {@link Ext.data.XmlReader XmlReader}:


+    errorReader: new Ext.data.XmlReader({
+            record : 'field',
+            success: '@success'
+        }, [
+            'id', 'msg'
+        ]
+    )
+
+ *

then the results may be sent back in XML format:


+<?xml version="1.0" encoding="UTF-8"?>
+<message success="false">
+<errors>
+    <field>
+        <id>clientCode</id>
+        <msg><![CDATA[Code not found. <br /><i>This is a test validation message from the server </i>]]></msg>
+    </field>
+    <field>
+        <id>portOfLoading</id>
+        <msg><![CDATA[Port not found. <br /><i>This is a test validation message from the server </i>]]></msg>
+    </field>
+</errors>
+</message>
+
+ *

Other elements may be placed into the response XML for processing by the {@link Ext.form.BasicForm}'s callback + * or event handler methods. The XML document is available in the {@link #errorReader}'s {@link Ext.data.XmlReader#xmlData xmlData} property.
