Hi everyone!  I am looking for resources to continue growing in my understanding of Salesforce Development.  I am aware of the Development Trailheads that are out there, and am looking for other resources that I can utilize.  In the past, I completed the Apex Academy course on Pluralsight, which was very helpful!  I currently have a pretty good grasp of basic triggers, and would like to keep building on this foundation.
If anyone could share their thoughts on the below questions about training resources or learning Salesforce Development, I would appreciate it!  Thank you!

1. What does the progression of things to know and master look like when learning Salesforce Development?
2. What are your favorite books, courses, blogs, podcasts or other instructional resources on Salesforce Development? If people had to teach themselves about development, what would you recommend they use?
3. Who are the most impressive but maybe lesser-known thought leaders, teachers, or trusted resources in the Salesforce Development space?  Who trained or influenced you in your work in development?
4. What are the biggest myths and mistakes that you see in learning Salesforce Development? What are the biggest wastes of time for people like me getting started?

I have a visualforce page that renders without problem using an iframe to create the table. This was created by a colleague that no longer works with us. We have developed an issue when using the print button in that it no longer renders all items in the iframe repeat, only the first. 
rendered lists:on click of print

<apex:page lightningStylesheets="false" showHeader="false" standardController="Apprentice__c" >

Any advice as to why this has changed would be appreciated
 

Hi All,
I am getting DUPLICATE_VALUE: the price definition already exist in the price book:[] error in test class. How do we resolve it?
I am getting above error when I use standard product Id in test class. Class is passing If I use custom pricebookId but failing while deploying.
Code:
Product2 pd = new Product2(Name='Product1',IsActive=true);
Insert pd;
Id standardPbId = Test.getStandardPricebookId();
PricebookEntry pbe = new PricebookEntry(Pricebook2Id=standardPbId,IaActive=true,UseStandardPrice=false,Product2Id=pd.Id,UnitPrice=1200);
insert pbe; // this line is failing
If I use below custom price book Id Instead standardPbId then it is passing but failing while deploying it.
Pricebook2 customPb=  new Pricebook2(Name='sample price book',IsActive=true);
insert customPb;
I tried below work arounds but didn't work.
Pricebook2 pb2 = new Pricebook2 (Id=Test.getStandardPricebookId(),IsActive=true);
update pb2;
Id standardPbId =[SELECT Id FROM Pricebook2 where IsStandard=true LIMIT 1].Id;
Did any one got this error and resolve it. please provide the solution for this.

Tooling API is failing to generate WSDL file
We are trying to generate the tooling Api Generate Tooling WSDL With Strongly Typed Enums  by clicking on the link. We are getting the following error :
--------------------------------------------------------------------------------------------
Type, erroneousFields, severity, elementName, acceptedDataType, dataType, fieldValue Errors with this extended error code have the following properties: erroneousElementApiName, erroneousElementType, erroneousFields, severity, assignmentName, operatorName, leftElementName, leftElementType, rightElementName, rightElementType Errors with this extended error code have the following properties: erroneousElementApiName, erroneousElementType, erroneousFields, severity, assignmentName Errors with this extended error code have the following properties: erroneousElementApiName, erroneousElementType, erroneousFields, severity, assignmentName, operatorName, leftElementName, rightElementName Errors with this extended error code have the following properties: erroneousElementApiName, erroneousElementType, erroneousFields, severity, elementName, dataType, incompatibleDataType Errors with this extended error code have the following properties: erroneousElementApiName, erroneousElementType, erroneous
-----------------------------------------------
The steps we followed:-
1.From SETUP -> API->Generate Tooling WSDL With Strongly Typed Enums.
2.Clicking on the link and getting above error.
3.In spite of the above error we downloaded the lately generated the tooling WSDL and save to the computer.
4.We tried to import the WSDL in SOUPUI by creating new Soup project and by selecting the generated tooling WSDL then we tried to generate sample request for all operations and we all getting the following errors:

Please help us to resolve the issue. #Tooling API #Integration #REST API

We have a trigger that changes a user's role based on changes made to the User.Division field, but as of Winter 2022 it is no longer working.  

I've added debug statements and I see that the code is assigning a new role id to the user record in a before update trigger context on the user object, but that change is no longer being saved to the user record.

Can anyone else confirm this? I haven't found an open issue yet and salesforce support doesn't help us at all when custom code is involved.

Create trigger handler on System

new record created When status includes mandatory  email

map contact__r.email primary email

Record is deleted when status includes mandatory Email

contact__r.email removed from primary email
 

I'm a very gambling person. But at the same time, I am profitable, which probably saves me from losing. If I see that the slot machine does not want to play today, I just go to another. Right now, I stuck on the https://betsofa-official.com. A couple of times have already managed to withdraw a decent amount.

I want to practise writing apex class, please can anyone provide a link where i can get different scenarios for writing apex classes

Hi
can we play Subway Surfers Mod APK offline game on app. Or anyone know any games of line on the app?
i downloaded the game https://techgara.com/subway-surfers (https://techgara.com/subway-surfers/)

I created 2 custom objects to display in Mobile.
The first: allright.
The second: I can't view it in Mobile, & I didn't find yet why.
What must I check end to end to review displaying actions & fix my issue?
Thanks for any return & Merry Christmas!
Pierre

I'm creating a case from the standard case creation page where I have kept one contact lookup field. So, before creating a case I can search the contact name, and then I will create the case, but I want to auto-populate contact phone number and email-based on the contact name. Is there any salesforce standard functionality I can use?

Actually, I want to create a website on RajaQQ (http://proboards46.com/)which will be based on games. Different games are providing points then you can withdraw the point by money
