Extjs 4 - Error Message as validator?

Question

I am locking for way to alert messages in Extjs4 to be just like validator alert ( red label with message beside the text field ).

I cannot use the validator because my error message should appear after press enter not just when type in text field.

You can use the markInvalid method to apply a custom error to a field.

But note that this mark will be cleaned when calling isValid
