-----------------------------------
Resolution: Fixed
Fix Version/s: 1.3.2
convertInput now checks if the type is already resolved or not
> AbstractTextComponent requires itself to be rendered before conversion happens

> Key: WICKET-1305
> URL: https://issues.apache.org/jira/browse/WICKET-1305
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.0-final
> Environment: wicket 1.3-final
> Reporter: Serge P. Nekoval
> Assignee: Johan Compagner
> Fix For: 1.3.2
>
>
> 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).
