If I tried to delete the account property first (e.g. exclude("account"). Is
this correct?), then adding using model.add("account"). The error becomes
Caused by: org.apache.tapestry5.ioc.internal.util.TapestryException:
Expression 'user.account' for class org.jecommerce.pages.Register is

Now it looks like the problem is because account is a read only field
(because I remove setAccount(String) method). Is there any chance to let it
automatically call e.g. constructor such as new User(account, name, ...)
(Though I think it is unlikely) ?
The bean model source used to create BeanModel is as below:
public BeanModel createBeanModel(Class clazz, String lang, String
country){
if(null == this.beanModelSource) throw new
NullPointerException("No
BeanModelSource configured!");
if(null == cache.get(BeanModel.class)){
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
URL url =
loader.getResource("messages_en_US.properties");
String path = url.getPath();
BeanModel model = null;
try{
ResourceBundle bundle = new
PropertyResourceBundle(new
FileInputStream(path));
model = beanModelSource.create( clazz, true,
new MessagesImpl(new
Locale(lang, country), bundle) );
//
}catch(IOException ioe){
ioe.printStackTrace();
}
cache.put(BeanModel.class, model);
}
return (BeanModel)cache.get(BeanModel.class);
}
Thanks for the help.
