Redirect to section of page

I want to redirect from another page to a section of visuaforce page:

I have used this in vf page(Definition is name of page):

<a href="#top">Go to top</a>

I have used this in the page where the button is located :
<a href="/apex/Definition#top">Test</a>

Even if i paste in address bar : https://c.na35.visual.force.com/apex/Definition?#test , still is not getting me to the sections .

It is simple in html . I dont know why it is not working on VF pages.

Thanks for looking at my problem

Confirm login and password within salesforce - Salesforce whitelist

In some part of our salesforce app, we require the user to confirm his password. We create a VF component that would call the following login() method (I think we pick this code from the web): 
public static String buildSoapLogin(String username, String password){
        XmlStreamWriter w = new XmlStreamWriter();
        w.writeStartElement('', 'login', 'urn:partner.soap.sforce.com');
        w.writeNamespace('', 'urn:partner.soap.sforce.com');
        w.writeStartElement('', 'username', 'urn:partner.soap.sforce.com');
        w.writeCharacters(username);
        w.writeEndElement();
        w.writeStartElement('', 'password', 'urn:partner.soap.sforce.com');
        w.writeCharacters(password);
        w.writeEndElement();
        w.writeEndElement();
        String xmlOutput ='<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Body>'
                    + w.getXmlString()
                    + '</Body></Envelope>';
        return xmlOutput;
    }
    
    public static Boolean login(String password) {
        HttpRequest request = new HttpRequest();
        String loginServer = (URL.getSalesforceBaseUrl().getHost().contains('cs') ? 'test' : 'login');
        request.setEndpoint('https://' + loginServer + '.salesforce.com/services/Soap/u/22.0');
        request.setMethod('POST');
        request.setHeader('Content-Type', 'text/xml;charset=UTF-8');
        request.setHeader('SOAPAction', '""');
        request.setBody(buildSoapLogin(UserInfo.getUserName(),password));
        
        if(Test.isRunningTest()) {
            if(password == 'password')
                return true;
            else
                return false;
        } else {
            return (new Http()).send(request).getBodyDocument().getRootElement()
              .getChildElement('Body','http://schemas.xmlsoap.org/soap/envelope/')
              .getChildElement('loginResponse','urn:partner.soap.sforce.com') != null;
        }
    }

To avoid needing the security token, we whitelisted all the ARIN, RIPE, APNIC IP addresses in the Network Access setup as described o, this Knowledge Article. But login may still fail. When checking the User login History we can read the following:
  • 2/3/2017 10:08:16 AM CET    Salesforce.com IP    Other Apex API    Failed: API security token required    N/A    test.salesforce.com
  • 2/3/2017 10:05:16 AM CET    136.146.210.252    Other Apex API    Success    N/A    test.salesforce.com    United States
The second IP addresse is part of the ARIN address ranges, so the login is succesful. But we don't know why the "Salesforce.com IP" case fails and we don't have any mean to know what is the actual IP address behind this label. Is there a hidden list of salesforce IP addresses?

Asynchronous callout to process json data returned from asp.net web service

I want to show data returned from an asp.net web service in a visualforce page using asynchronous callout.
I have done following things to achieve the above
1. Created an asp.net web service to return data from SQL Server table in json format.
2. Generated wsdl file from the web service.
​3. Parsed wsdl to generate an apex class.
4. Created a controller apex class to call the methods from class generated from wsdl.
5. Designed a visualforce page to show the output.

Currently I am calling the method synchronously from controller which is showing the result but it is causing a page postback, taking some time to load the results, showing Request Time Out Exception at times.

So I want to call the method asynchronously now.
Here is my method.
public class AsyncGetCustomer {
            public class GetCustomerJsonResponse_elementFuture extends System.WebServiceCalloutFuture {
        public String getValue() {
            getCustomer.GetCustomerJsonResponse_element response = (getCustomer.GetCustomerJsonResponse_element)System.WebServiceCallout.endInvoke(this);
            return response.GetCustomerJsonResult;
        }
    }

    public class AsyncGetCustomerSoap {
        public String endpoint_x = 'ServiceLink';
        public Map<String,String> inputHttpHeaders_x;
        public String clientCertName_x;
        public Integer timeout_x;
        private String[] ns_map_type_info = new String[]{'Url', 'ServiceName'};

        public AsyncGetCustomer.GetCustomerJsonResponse_elementFuture beginGetCustomerJson(System.Continuation continuation) {
            getCustomer.GetCustomerJson_element request_x = new getCustomer.GetCustomerJson_element();
            return (AsyncGetCustomer.GetCustomerJsonResponse_elementFuture) System.WebServiceCallout.beginInvoke(
              this,
              request_x,
              AsyncGetCustomer.GetCustomerJsonResponse_elementFuture.class,
              continuation,
              new String[]{endpoint_x,
              'http://uniweb.klinkjewellery.com/GetCustomerJson',
              'http://uniweb.klinkjewellery.com/',
              'GetCustomerJson',
              'http://uniweb.klinkjewellery.com/',
              'GetCustomerJsonResponse',
              'getCustomer.GetCustomerJsonResponse_element'}
            );
        }
}

Here is my controller class
public with sharing class ctrlAsynchCustomer {
    AsyncGetCustomer.GetCustomerJsonResponse_elementFuture custFuture;
    public String result {get; set;}
   
    public Continuation startRequest(){
        Integer TIMEOUT_INT_SECS = 60;
        Continuation cont = new Continuation(TIMEOUT_INT_SECS);
        cont.continuationMethod = 'processResponse';
        AsyncGetCustomer.AsyncGetCustomerSoap custService = new AsyncGetCustomer.AsyncGetCustomerSoap();
        custFuture = custService.beginGetCustomerJson(cont);
        return cont;
    }     
        
    //Callback method
    public void processResponse(){
        result = String.valueOf(custFuture.getValue());
        // Return null to re-render the original Visualforce page
       return null;
    }
}

Here is my visualforce page
<apex:page controller="ctrlAsynchCustomer" tabStyle="Customer__tab">
    <apex:form >
        <!-- Invokes the action method when the user clicks this button. -->
        <apex:commandButton action="{!startRequest}" Value="Start Request" rerender="result"/>
    </apex:form>
    <!-- This output text component displays the callout response body. -->
    <apex:outputText id="result" value="{!result}"></apex:outputText>
</apex:page>

Now whenever I click the button the following error is shown.

Visualforce Error
Help for this Page
System.CalloutException: Web service callout failed: Unexpected element. Parser was expecting element 'http://schemas.xmlsoap.org/soap/envelope/:Envelope' but found 'http://www.w3.org/1999/xhtml:html'

Class.AsyncGetCustomer.GetCustomerJsonResponse_elementFuture.getValue: line 30, column 1
Class.ctrlAsynchCustomer.processResponse: line 28, column 1

When i checked the developer console for the logs of the operation i found 2 logs out of which one was successful and the other was not, following is the debug result of the successful log.

here is the exception shown at unsuccessful log.

Close Tab after Save - Service Console

Hi there!

I'm looking for a way to automatically close a record tab in Salesforce Service Console when I create a new record.

I'm using a custom object called Configuration Resource(s), these are added to the parent record (Configuration object), from a related list on the Configuration object page layout.
Ideally, I need to be able to have the tab that opens when the new configuration resource is created, close after saving, is this possible?

I keep getting this error: "Type is not visible: Opportunity". How do I fix this?

I think it has to do with my Apex test classes - I tried to change some classes from "private" to "public" but the classes wouldn't save and just show this error instead. (I am going through Apex Academy on pluralsight, so this is the example from there - the suggested method was "private class" in line 2, but it still gives me the error when I try to save it as "public class".
 
@isTest
private class LeadingCompetitorTest {
    
    @isTest static void createOppWithCompetitors() {
        // Create an opportunity and set required fields
        Opportunity opp = new Opportunity();
        opp.Name        = 'Big Deal';
        opp.CloseDate   = Date.today();
        opp.StageName   = 'Prospecting';

        // Set competitor price fields
        opp.Competitor_1_Price__c = 5000;
        opp.Competitor_2_Price__c = 15000;
        opp.Competitor_3_Price__c = 25000;

        // Set competitor fields
        opp.Competitor_1__c = 'Amazon';
        opp.Competitor_2__c = 'Google';
        opp.Competitor_3__c = 'Microsoft';

        insert opp;
        System.debug('Opportunity ' + opp.Name + ' inserted with all comeptitor fields populated.');

Add "Change Owner" to Lead List view in Lightning

Hello,

I am rolling out Lightning Experience to everyone in my organization and I am concerned about the lack of standard buttonds in the List View Search Layout for Leads.

One of the Standard buttons that is used very often in Classic is the "Change Owner" button.  Even though the checkbox is checked in this view, I am not seeing it on my Leads page in Lightning.

These are the buttons I have enabled in the Setup > Object manager > Leads > Search Layout > List View (you can see that "Change Owner" is checked.)

User-added image

And yet the Change Owner button does not appear on the Lightning page:
User-added image
I know it is possible because I have seen it in the release notes: https://trailhead.salesforce.com/en/winter_17/winter_17_sales
User-added image
What can I do to add the "Change Owner" feature back into the Leads List View?

Thanks.

I am still getting this error:

Challenge Not yet complete... here's what's wrong:
The campingList JavaScript helper isn't saving the new record to the database or adding it to the 'items' value provider.

My App save the new record into the database and add it to the "items" list.
Thanks for your answers!

The campingList JavaScript controller isn't setting the 'item' as a parameter or saving the record correctly.

My code is as follows:
