How do I properly catch and display error messages in VisualForce
I have a visualforce pag where I override the Save command.
Since I am overriding the Save command. In the script I utilize the Update DML statement, however I have validation that used to work fine and display the error in my VisualForce page when I used the standard controller.
Now I believe I need to re-validate in my code, catch the same error condition and throw the error message to the visualforce page so it shows up where the validation error message normally would.
How do I do this?
You code must be followed following structure
In VF page you have to use <apex:pageMessages> tag where you want to display your error message
