Validation Rule Visual Force Page

Question

I am trying to display validation rules errors in a VisualForce page I have, but the message isn't showing.

I have the <apex:pageMessages /> tag inside my page and it works for required fields errors, but nothing works for validation rules.

My controller is a standard one, so I can't do a try/catch block to explicitly write the error to ApexPages.addMessage()

Any ideas on this?

Validation rules do cause page messages, but only after Visualforce validation and standard validation (e.g. database-required fields). You'll need to get past any Visualforce validation rules and standard validation rules before you can see custom validation errors.
