Extjs 4 - Error Message as validator?

Вопрос
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

You should be using the validator like normal, just set validateOnChange: false. The field will still validateOnBlur because that's set to true by default. I believe enter triggers the blur of the field which will in turn validate the field with this change.
