Problem with h:message and richfaces

Hello,
I noticed a strange problem occurring with my richfaces application. It is as follows:
I have a contact form with "real-time" validation of each field. When a valid submission of the form occurs, the form is reRendered and strangely, the first field shows a validation passed status even though it is empty.

Here is my jsp:
