Hello,

I'm doing a 'Visualforce Basics' module and I'm stuck at 'Use Standard Controllers' Unit (link here).
I created a page with the following code:
 
<apex:page>
    <apex:pageBlock title="Account Summary">
        <apex:pageBlockSection>

        </apex:pageBlockSection>
    </apex:pageBlock>
</apex:page>

Then I opened a page via the "Preview" button in a Developer Console and opened a JavaScript console in Chrome where I typed:

$A.get("e.force:navigateToURL").setParams({"url": "/apex/AccSum"}).fire();
And I got the following error:
Uncaught ReferenceError: $A is not defined at <anonymous>:1:1
 

Both the snippets are copied from the Unit's sections, I didn't change anything except the page's name - 'AccSum'. I tried all of the above in a Firefox which also did not work.

Does anyone know what's going on?

When I try to authenticate to SalesForce in order to get access to the data I get this message: "retry your request".
The authentication was successful till this morning. I know that for unsuccessful authentication you should receive different error (authentication failure).

How to overcome this issue?

This is my code:
 string securityToken = ConfigurationManager.AppSettings["SecurityToken"];
            string ConsumerKey = ConfigurationManager.AppSettings["ConsumerKey"];
            string ConsumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"];
            string Username = ConfigurationManager.AppSettings["Username"];
            string Password = ConfigurationManager.AppSettings["Password"] + securityToken;
            string IsSandboxUser = ConfigurationManager.AppSettings["IsSandboxUser"];

            var url = IsSandboxUser.Equals("true", StringComparison.CurrentCultureIgnoreCase)
                ? "https://test.salesforce.com/services/oauth2/token"
                : "https://login.salesforce.com/services/oauth2/token";

            var auth = new AuthenticationClient(new HttpClient());
            try
            {
                await auth.UsernamePasswordAsync(ConsumerKey, ConsumerSecret, Username, Password, url);
            }
            catch (Exception ex)
            {
                throw;
            }
Hi All,

I've been stuck with this error for 2 days already.

I've been trying to test a fairly simple REST code in my workbench. But for some weird reason(s), it always show this error (attached)

Here's my code:
@RestResource(urlMapping='/v1/accounts/*')
global with sharing class SampleREST{
  
    @HttpGet
    global static AccountWrapper doGet() {
        RestRequest req = RestContext.request;
        RestResponse res = RestContext.response;
        
        AccountWrapper response = new AccountWrapper();
        
        response.acctList = [SELECT Id, Name FROM Account];
        response.status = 'Success';
        
        return response;
    }
    
    global class AccountWrapper{
        public List<Account> acctList;
        public String status;
        public String message;
        
        public AccountWrapper(){
            acctList = new List<Account>();
        }
    }
}

Of all the articles I've checked, they all point me into 1 direction and it hasn't worked either.

So I was thinking that it might be something that I setup or forget to setup before I had my class created?

Appreciate your help on this.User-added image
 
I've completed the challenge, it has 100% coverage. I've checked all the method names. The URL is valid. I've used Work Bench and curl to test and even tested with multiple Accounts with and without contacts.

I know on other challenges, punctionation was important.  What about the defination of the return? Are there expected names?

I built a class to hold Account ID & Name along with a List of Contact names and IDs. Is this my issue?  Anyone else have a challenge with this challenge?


Any help or hints will be appreciated.

Here are snippets of my code:

@RestResource(urlMapping='/Accounts/*/contacts')
global with sharing class AccountManager {

....

global class APIAccount {
        public ID Id;
        public String Name;
        List<APIContact> Contacts;

...

@HttpGet
    global static APIAccount getAccount() {
        RestRequest request = RestContext.request;
...

got this when following trailhead use standard controller instructions (working through section: find a record ID

any help fixing this?

Invalid 'X-Frame-Options' header encountered when loading 'https://na35.salesforce.com/apexpages/devmode/devConsoleViewStateMetadataReceiver.apexp?sfdcIFrameOrigin=https%3A%2F%2Fc.na35.visual.force.com': 'ALLOW-FROM https://c.na35.visual.force.com' is not a recognized directive. The header will be ignored.
The WSDL generated for an Apex Class method using the webservice keyword may be missing required complex types.

Take the example:
global class RetrieveOpportunity {
  webservice static Opportunity retrieveOpportunity(Id opportunityId) {
    return new Opportunity();
  }
}

This will generate a WSDL with elements like:
 
<xsd:element name="BillingAddress" minOccurs="0" type="tns:address" nillable="true"/>

The issue is that there is no address complex type in the WSDL tns namespace (http://soap.sforce.com/schemas/class/DFB/RetrieveOpportunity in this case).

This results in errors like:
Error: type 'address@http://soap.sforce.com/schemas/class/RetrieveOpportunity' not found.
Source - WSDL generated from apex can't import to SoapUI (http://salesforce.stackexchange.com/q/56005/102)
and
Error 1 Unable to import binding 'getLeadInfoBinding' from namespace 'http://soap.sforce.com/schemas/class/getLeadInfo'. App_WebReferences/WebReference/

Source - Issue with Adding reference Webservice WSDL to VS2010 (http://salesforce.stackexchange.com/q/53329/102)

The currently solution is to manually add the missing complex types to the xsd:schema with the required targetNamespace.
 
<!-- Compound datatype: Address -->
        <complexType name="address">
            <complexContent>
                <extension base="tns:location">
                    <sequence>
                        <element name="city" type="xsd:string"  nillable="true" />
                        <element name="country" type="xsd:string"  nillable="true" />
                        <element name="countryCode" type="xsd:string"  nillable="true" />
                        <element name="postalCode" type="xsd:string"  nillable="true" />
                        <element name="state" type="xsd:string"  nillable="true" />
                        <element name="stateCode" type="xsd:string"  nillable="true" />
                        <element name="street" type="xsd:string"  nillable="true" />
                    </sequence>
                </extension>
            </complexContent>
        </complexType>

<!-- Compound datatype: Location -->
        <complexType name="location">
            <sequence>
                <element name="latitude" type="xsd:double"  nillable="true" />
                <element name="longitude" type="xsd:double"  nillable="true" />
            </sequence>
        </complexType>

Can this be raised as an Apex API bug?
How can I delete all the records of a custom object in Developer Edition?

If you have a SOQL statement with ORDER BY and a LIMIT 100 clause, which executes first?  Does it order all records and then take the first 100 records or does it do the LIMIT first and then ORDER BY?
