>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 1.3.0-final

> The bug is reproduced as follows:
> 1. Use StatelessForm.
> 2. Use compound model, eg CompoundPropertyModel. In this case, form components are not initially aware of their model types.
> 3. Use any text component inside, eg TextField
> What happens:
> 1. In StatelessForm, form processing occurs BEFORE components were actually rendered.
> 2. BUT AbstractTextComponent guesses its model type ONLY in onBeforeRender().
> 3. onBeforeRender() never gets called, so text component doesn't know its actual type and cannot convert properly.
> 4. Everything crashes because of incorrect type (validators and form submission is working wrong).
> Obviously, this processing sequence needs to be fixed (eg retrieve model type early or check for stateless forms explicitly).
