System.SObjectException: SObject row was retrieved via SOQL without querying the requested field: Employee__c.Name

Answer 1

What you can try to do:

1. Try to use the addFields() method of the StandardController class. That will explicitly add fields to the record:

public testPage(ApexPages.StandardController controller) {
    ...
    controller.addFields(new String[]{'Id','Name'});
    this.pme = (Employee__c )controller.getRecord();

2. Use this. if initializing an variable from the standard controller in constructor:

this.pme = (Employee__c )controller.getRecord();

I hope this helps!
