Kamil created WICKET-6383:
-----------------------------
Summary: PropertyValidator throws Exception when Model is empty
Key: WICKET-6383
URL: https://issues.apache.org/jira/browse/WICKET-6383
Project: Wicket
Issue Type: Bug
Components: wicket-bean-validation
Reporter: Kamil
During creation of PropertyValidator if Model is empty (it is set during
runtime):
{code}
IModel<User> model = new Model<>();
CompoundPropertyModel<User> compound = new
CompoundPropertyModel<>(model);
TextField<String> tf = new TextField<>("email",
compound.bind("email"));
tf.add(new PropertyValidator<>());
add(tf);
{code}
an exception is thrown:
{code}
Last cause: Could not resolve Bean Property from component: [TextField
[Component id = email]]. (Hints:) Possible causes are a typo in the
PropertyExpression, a null reference or a model that does not work in
combination with a IPropertyResolver. Model :
Model:classname=[org.apache.wicket.model.PropertyModel]:nestedModel=[Model:classname=[org.apache.wicket.model.CompoundPropertyModel]:nestedModel=[Model:classname=[org.apache.wicket.model.Model]:object=[null]]]:expression=[email]
WicketMessage: Error attaching this container for rendering: [UserPanel
[Component id = formPanel]]
{code}
without this line:
{code}
tf.add(new PropertyValidator<>());
{code}
everything works
