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
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).
