> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-hibernate
> Affects Versions: 5.0.11
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
> Priority: Critical
>
> If a property is null and that property is value encoded (perhaps due to a
> RadioGroup), then an NPE occurs:
> #
> sun.reflect.UnsafeFieldAccessorImpl.ensureObj(UnsafeFieldAccessorImpl.java:36)
> #
> sun.reflect.UnsafeObjectFieldAccessorImpl.get(UnsafeObjectFieldAccessorImpl.java:18)
> # java.lang.reflect.Field.get(Field.java:357)
> #
> org.hibernate.property.DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:32)
> #
> org.apache.tapestry.internal.hibernate.HibernateEntityValueEncoder.toClient(HibernateEntityValueEncoder.java:46)
> #
> org.apache.tapestry.corelib.components.RadioGroup.setupRender(RadioGroup.java:146)
> #
> org.apache.tapestry.corelib.components.RadioGroup.setupRender(RadioGroup.java)
> The ValueEncoder should check for null, and return null.
