How to check if any error has been added to a Salesforce record?

Hi Tanu,

The addError methods in a Visualforce context will also add to the Apex Page messages collection, which you can access via the ApexPages.getMessages method.

Use the apexMessages on the visualforce page and apex controller :-

sObject testRecord = new sObject();
testRecord.addError('Some error');
testRecord.A_Number__c.addError('Field error');
for(ApexPages.Message message : ApexPages.getMessages())
System.debug(message.getComponentLabel() + ' : ' + message.getSummary());
