Reset Form Error Inside a Dialog

[vortura]

I've created a component that presents a Dialog containing the form. Submitting the form posts to a REST API, which can return an error. I'm using the $page.form to check for the error and display it next to the submit button.

If I submit bad data to the form, the error message is shown as expected. If I close the dialog at this point however, and then reopen it, the error message is still there next to the submit button. How would I go about "resetting" the dialog when it is closed, such that when it is reopened, there is a fresh, empty form and no error message displayed?
