schema object - parsing issues in different mobile views

[Lee]

I have a datasource for messages and list a snippet of all the messages on one mobile view and view the full message in another mobile view.   I use the schema: parse function to make a snippet of the message on the list messages page.  This appears to be working well, however I do get an error message, "message is undefined" whenever I update the datasource.

I also have a similar error  "rawDate.split is not a function",  which is also initiated from the schema and again, only occurs when the datasource is updated.

Anyone any ideas why this is and what I can do to fix it?

var messageDataSource = new kendo.data.DataSource({

  

  transport: {

      read: "/messages/data",

      dataType: "json",

      update: {

          url:  function() {

              var url = "/messages/markasread/" + message_id + "/" + message_read;

              if (message_read == 0){

                if(unread_messages != 0){

                    var new_unread_messages = unread_messages-1;

                  } else {

                    var new_unread_messages = unread_messages;  

                  }

              } else if (message_read == 1){

                var new_unread_messages = unread_messages+1;

              }

              $("span#unread_messages").html(new_unread_messages); 

              $("span#unread_messages_hp").html(new_unread_messages);                            

               

              return url;

          },

          type: "POST",

          dataType: "json"

      },               

      destroy: {

          url:  function() {

              var delurl = "/messages/delete/" + message_id;

              return delurl;

          },                       

          type: "DELETE",

          dataType: "json"

      }

               

  },

 error: function(e) {

   alert(e.responseText);

 },

 sort: { field: "created", dir: "desc" },                                        

  schema: {

   

    model: {

        id: "id",

        fields: {

            message: { type: "string" },

            shortMessage:{ type: "string"},

            customer_name: { type: "string" }, 

            customer_telephone: { type: "string" },

            ip: { type: "string" },

            created: { type: "date", parse: parseDate },

            formatedCreated: { type: "string"},

            shortCreated: { type: "string" },

            email: { type: "string" },

            isnew: { type: "string" }  

           }

       },

      parse : function(data) {

              $.each(data, function(i, val){

                 //reduce text of message if being used for list

                 var message = val.message;    

                 if (message.length > 100){

                   var shortText = jQuery.trim(message).substring(0, 100).split(" ").slice(0, -1).join(" ") + "...";

                 } else {

                   var shortText = message;

                 }                     

 

                val.shortMessage = shortText;      

   

                //format the date

                var created = parseDate(val.created);

                 

                val.shortCreated = formatDate(created);

                 

                val.formatedCreated = val.created;

              });

          return data;

          }             

   }                      

 });

function parseDate(rawDate) {

    var bits = rawDate.split(/[-\s:]/);

    var year =  bits[2];

    var month = bits[1]-1;

    var day = bits[0];

    var hour = bits[3];

    var minute = bits[4];

    var validDate = new Date( year, month, day, hour, minute );

     

   return validDate;
