Major Description
When triggering validation messages on a form component, they aren't cleared anymore when afterward we fix our validation problem.
The following code demonstrates this issue by making a form with a single text field that is set as required. First, we submit the form without filling in the field. We expect that to cause an error. Which it does. Then, we set a value in the field, and submit again. We expect that to pass validation. It does not, however.
Instead, we get this exception:
junit.framework.AssertionFailedError: expect no error message, but contains
Field 'field' is required.
at junit.framework.Assert.fail(Assert.java:47)
at junit.framework.Assert.assertTrue(Assert.java:20)
