Hi all,

I am trying to deserialize a jason string in a class, like this :
    public static submit(String objString)
Map<String,Object>  dataListMap = (Map<String,Object>)JSON.deserializeUntyped(objString);
        List<Object> dataList = (List<Object>)dataListMap.get('question');
       	for(Object objSobject : dataList){
            Map<String, Object> p = (Map<String, Object>) objSobject; 

Following is the JASON string :
"ansList": [ { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowKQAS", "Name": "Highly Satisfied" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowZQAS", "Name": "Does not work" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowUQAS", "Name": "Not Satisfied" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowPQAS", "Name": "Satisfied" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowFQAS", "Name": "Very Impressed" } ], "question": { "Id": "a228E000000CcvAQAS", "Name": "SQ-000007", "CP_Question__c": "The products offered in the stored", "CP_AnswerType__c": "5 Radio Buttons", "Survey__c": "a208E000000CfOzQAK", "Survey_Answers__r": [ { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowKQAS", "Name": "Highly Satisfied" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowZQAS", "Name": "Does not work" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowUQAS", "Name": "Not Satisfied" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowPQAS", "Name": "Satisfied" }, { "CP_SurveyQuestion__c": "a228E000000CcvAQAS", "Id": "a238E000000CowFQAS", "Name": "Very Impressed" } ] }, "strSelectedAnswer": "Very Impressed"

I get this error in the debug :
System.TypeException: Invalid conversion from runtime type List<ANY> to Map<String,ANY>

I am using JSON.deserializeUntyped and from the VF I am passing angular JS list to the remote function like :angular.toJson($scope.relatedQuesAnsList, true)

Can any one let me know the what i am doing wrong.
Hi All,

I have a requirement where I need to show task list of a case on visualforce page with checkbox's for each task. When I select the tasks, On select of the check box I need to update the task status in the database and refresh the table back on the visualforce page. I have written the logic to display the task list on the VF. How can I update the database on select of the checkbox and refresh the page.

public class RelatedTaskController {
    public List<taskWrapper> taskList {get; set;}
    public RelatedTaskController(){

	public List<taskWrapper> getTasks() {
		if(taskList == null) {
			taskList = new List<taskWrapper>();
			for(Task c: [select Id, Owner.Name,Status,Subject from Task where WhatId =: '5008E000001EOg6QAG']) {
				taskList.add(new taskWrapper(c));
		return taskList;
         public class taskWrapper {
		public Task tsk {get; set;}
		public Boolean selected {get; set;}

		public taskWrapper(Task t) {
			tsk = t;
			selected = false;

Visualforce page:
<apex:page controller="RelatedTaskController">
    <apex:form >
        <apex:pageBlock >
           <apex:pageBlockTable value="{!taskList}" var="t" id="table">
                <apex:column >
                    <apex:inputCheckbox value="{!t.selected}"/>
                <apex:column value="{!t.tsk.Owner.Name}" />
                <apex:column value="{!t.tsk.Subject}" />
                <apex:column value="{!t.tsk.Status}" />



I have a custom details page button which pops out a visualforce page in an Iframe. I am using jquery postmessage and receivemessage to communicate between the cross domain. I am not able to understand how to debug the postmessage and receivemessage. I have two buttons "OK" and "Close". On click of "OK" I want to run a logic and upon "close" the popup should be closed and the parent record window should be displayed. Following is the code I am using reffered from the link (http://www.valnavjo.com/blog/modal-dialog-on-a-standard-salesforce-page/) :

I am using custom ORG URL

Custom button code :
{!REQUIRESCRIPT ('/resource/Jquery/Jquery/postmessage/jquery.ba-postmessage.min.js')}
{!REQUIRESCRIPT ('/resource/Jquery/Jquery/bbq/jquery.ba-bbq.min.js')}


function requireCssFile(filename) {
    var fileref = document.createElement('link');
    fileref.setAttribute('rel', 'stylesheet');
    fileref.setAttribute('type', 'text/css');
    fileref.setAttribute('href', filename);

var j$ = jQuery.noConflict();
var iframeurl = '{!URLFOR("/apex/CPSolicitorReassignPopup")}';
var child_domain = iframeurl.substring(0, iframeurl.indexOf('/', 9));
var parent_domain = window.location.protocol + '//' + window.location.host+ '/' +'{!Case.Id}';

        var cross_result = j$.deparam(e.data);
        if (cross_result.action == 'Close') {

var j$modalDialog = j$('<div></div>')
       .html('<iframe id="iframeContentId" src="' + iframeurl + '?parent_domain=' + parent_domain + '" frameborder="0" height="100%" width="100%" marginheight="0" marginwidth="0" scrolling="no" />')
            autoOpen: false,
            title: 'Alert!',
            resizable: false,
            autoResize: true,
            modal: true,
            draggable: false
Visualforce page :

            j$(document).ready(function() {
                j$('input[id$=btnCloseModalDialog]').click(function(event) {

                var cross_result = new Object();
                cross_result.action = 'Close';
    <apex:form >
        <apex:panelGroup >
            Please confirm as this action will close the current Instruction Case from the Solicitor and close any open tasks.
            Once confirmed new Instruction page will be presented for you to reassign &amp; confirm the instructions.
