<Apex:pageMessages/> not showing errors

Question

I'm having problem showing errors in my page, I have validation rule on the custom_object__c which I have created and its Active but when I try to save the page instead of getting the validation rule error on my apex:pageMessages I'm getting Visualforce Error

here is the erorr showing:

System.DmlException: Update failed. First exception on row 0 with id XXXXX; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION ]

Error is in expression '{!Save}' in component in page employeePage: Class.EmployeeCtrl.Save:

What do I need to do to show error on apex:pageMessages?

Answer 1

You should try like this :

try {  
    insert Account;
} 
catch (DMLException e) {
    ApexPages.addMessages(e);
}
