No rerender after validation failed
I have the following problem.
I have two required field x1 and x2 and a save button. On every change x.swap is called via a4j:support. If both field have not null value then swap swaps the value of the two field.
Everything works fine except there is a validation error. After that the fields are not rerendered.
Scenario: I write 1 into the first field (x1) then I click on save. Value is required message comes. Now I write 2 into the second field (x2). The x.swap is called and the second field is rerendered but the first field does not. It still shows 1 but the field x.x1 have the value 2. I debugged and x.getX1() is not even called after I clicked save.
In our project this happens everywhere where a field is calculated based on other fields. After a validation error these fields stop rerendering.
We use Seam 2.0.2.SP1 + JBoss 4.2.3.GA + RichFaces 3.2.2.SR1. But I tried different Seam and RichFaces versions and got the same result.
I ran out of any idea. So any help is appreciated.
