Hi,

I'm using same controller for 2 vf pages.The data entered on one vf page wanted to display on other vf page.
When I try to display data on other vf page getting NULL.I'm using <Apex:Actionfunction> for passing the passing the perameter
and calling the method defined in Controller.Also used Actionpoller to rerender the certain portion on vf page.

Help is appreciated in advance !

Here is the code..
---------- Controller method --------------------
 public void echoVal()
    {
     system.debug('After 30 Seconds==>'+enteredText1);
     val = 'You have entered :  - '+enteredText1;
     system.debug('Testing..parameter==>'+val);
    }  

-------------- VF page1 (getting data from user) ---------------------
  Enter SR_Description :
    <apex:inputText id="txt1" />
      <apex:outputPanel id="resultPanel">
        <b><apex:outputLabel value="{!val}" /> 
     </b></apex:outputPanel>
 <apex:actionFunction name="echo" action="{!echoVal}" reRender="resultPanel">
        <apex:param name="firstParam" assignTo="{!enteredText1}" value="" />
      </apex:actionFunction> 

    <apex:outputLabel rendered="{!uploadFlag}" value="{!uploadMessage}"></apex:outputLabel>
 <!-- <center><apex:commandButton value="Save" onclick="CallContr();"/>   -->
 <center><apex:commandButton value="Click here" onclick=" return callActionMethod();"/>
   <script>
    
      function callActionMethod()
      {
        alert('working..');
         var txtVal1 = document.getElementById("{!$Component.theForm.SRpageblock.pgbSec.txt1}").value;
         alert(txtVal1 );
         /*Below Method is generated by "apex:actionFunction" which will call Apex Method "echoVal" */
         echo(txtVal1); 
         return false; 
      }
</script>

------------- VF Page (Where data is displaying) -------------------
 <apex:form id="frmSRdescription">
    <apex:actionPoller reRender="frmSRdescription" interval="30" rendered="true" action="{!echoVal}"/>
        <apex:pageBlock >
                <apex:outputLabel value="{!test}"></apex:outputLabel>
                <b><apex:outputLabel value="{!val}" /></b>  <b><apex:outputLabel value="{!enteredText1}" /></b>
 

Here is my code.. and It works perfectly for sorting on Name field.

I want to sort on Name field,If Names are same ,Sorting should be on Email field.

 global class cContact implements Comparable{
        public Contact cnt {get; set;}
        public Boolean cntSelected {get; set;}
        public cContact(Contact c) {
            cnt = c;
            cntSelected = false;
        }
        global Integer compareTo(Object compareTo) {
            cContact compareToCnt = (cContact)compareTo;
            String s1=cnt.Name;
            String s2=compareToCnt.cnt.Name;
            return (s1.compareTo(s2));       
        }
    }

Help is appreciated in advance.

Is it possible to do bulk record update in my Child Record using Process Builder and Flows Combination ?

My Scenario is - Whenever the Account Owner Changes (in Bulk), the related Contact Owners should be changed. 

Can someone help me how to achieve this using Process Builder and Flows Combination ?

Create an Apex class that returns an array (or list) of strings: 
Create an Apex class that returns an array (or list) of formatted strings ('Test 0', 'Test 1', ...). The length of the array is determined by an integer parameter.The Apex class must be called 'StringArrayTest' and be in the public scope.
The Apex class must have a public static method called 'generateStringArray'.
The 'generateStringArray' method must return an array (or list) of strings. Each string must have a value in the format 'Test n' where n is the index of the current string in the array. The number of returned strings is specified by the integer parameter to the 'generateStringArray' method.

MyApexClass to above Challenge:

public class StringArrayTest {
    
    public static List<string> generateStringArray(Integer n)
    {
        List<String> myArray = new List<String>();
        
        for(Integer i=0;i<n;i++)
        {
            myArray.add('Test'+i);
            System.debug(myArray[i]);
        }
        return myArray;
        
    }

It's compile and execute as per requirement in Developer console. But Traihead showing the below error:

Challenge not yet complete... here's what's wrong: 
Executing the 'generateStringArray' method failed. Either the method does not exist, is not static, or does not return the proper number of strings.

Anyhelp would be greatly appreciated. Thanks.
