Hello. I save a form by a Ext.Ajax.request. My problem is that I have to do a server-side form-validation because some errors depending on a actual database-query (like some fields have to be unique and another user could have graped this value between form-loading and form-saving).

What is the way to show JsExt-Errors then beside the fields of the form? Is there something build-in I could use or do I have to set every error "manually" by my own code?
