How to resolve some Salesforce issues (Winter ‘18 release)

Like any large system, some issues may occur in Salesforce. In this article, we'll consider some of them along with solutions found by our Salesforce development team:

  1. Difference between operating Lightning and Classic interfaces. Buttons, Links and Actions defined on the Layout page are not displayed in the Lightning interface;
  2. An issue with connection to Salesforce using SOAP API WSDL file from a .NET project;
  3. Visualforce page cannot perform the action on the controller after clicking the button linked to this action, if the page has unfilled required fields.

Difference between work of Lightning and Classic interfaces

Salesforce has two different interfaces – Lightning and Classic:

1Lightning _ui


2Classic _UI


Each object on Salesforce has the ability to create its own Buttons, Links and Actions, that users can locate in the object’s layout page and use these on the Object edit page.

3 Buttons Links And Actions

Buttons, Links and Actions on Setup -> Object Manager

For the Classic version, this works as expected:

But for Lightning, you cannot find these buttons and links:

If you want to create the same button on the Lightning interface without programming, you can create Action or Global Action and bind this Action or Global Action to the object's Layout page.

For applying your own global actions for Lightning:

  1. Click the 🔧 icon on the “Salesforce Mobile and Lightning Experience Actions” section for an override default list of global actions;
  2. Add your own global action to the list section “Salesforce Mobile and Lightning Experience Actions”.

An issue with connecting to Salesforce using SOAP API WSDL file from .NET project

Salesforce, like any large system, has a set of APIs - REST, SOAP, etc. At the moment (Winter’18 release), there is an issue when connecting to Salesforce from the .NET project using the SOAP API. The fact is that the WSDL file, received from the API page in the Setup menu, generates a runtime error when trying to connect to Salesforce:

Unable to generate a temporary class (result=1).
error CS0030: Cannot convert type 'xxx.Salesforce.ListViewRecordColumn[]' to 'xxx.Salesforce.ListViewRecordColumn'

7 WSDL API On Setup Menu

To solve this issue, you can modify your WSDL file. Add row: 

to complexType ListViewRecord.

As result you’ll get the following text: 

This is how you handle the described issue. 

Visualforce page cannot perform the action on the controller after clicking to the button that is linked with this action, if the page has some unfilled required fields

This issue occurs if we want to perform some action on the form on which the required field is located, by clicking the button. Suppose there’s a Visualforce page that allows you to create and edit the fields Account Name, Phone, Industry from the Account object. The Account Name field is a required field. Also on the form we have two buttons - Save, to save the account and Do Action to perform any action (In our case - to write to the log).

8 Example Of Visualforce Page

Example of Visualforce page

To demonstrate an error create:

  1. Visualforce page with the following code:
  2. Custom Apex controller:
    public class AddEditAccountCustomController {
        String paramValue;
    	public Account account { get; private set; }
        public AddEditAccountCustomController() {
            Id id = ApexPages.currentPage().getParameters().get('id');
            account = (id == null) ? new Account() :
                [SELECT Name, Phone, Industry FROM Account WHERE Id = :id];
        public PageReference save() {
            try {
            } catch(System.DMLException e) {
                return null;
            //  After successful Save, navigate to the default view page
            PageReference redirectSuccess = new ApexPages.StandardController(Account).view();
            return (redirectSuccess);
        public String getParamValue(){
            return paramValue;
        public void setParamValue(String paramValue){
            this.paramValue = paramValue;
        public void doAction() {
            System.debug('Account Name Before :'+ this.paramValue);


When a user clicks the “Do Action” button while the “Account name” field is empty, the button doesn’t work properly. 

To solve this issue we can use the Visualforce tag <apex:actionRegion>. An area of a Visualforce page that demarcates which components should be processed by the server when an AJAX request is generated. Only the components in the body of the <apex:actionRegion> are processed by the server, thereby increasing the performance of the page.

After solving the issue Visualforce page code looks like this.
