Howard M. Lewis Ship reassigned TAP5-1227:
------------------------------------------
Assignee: Howard M. Lewis Ship
> Binding a parameter whose type is primitive to null results in a difficult to
> understand NullPointerException
> -------------------------------------------------------------------------------------------------------------
>
> Key: TAP5-1227
> URL: https://issues.apache.org/jira/browse/TAP5-1227
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.2.0
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
>
> NPE is appropriate, but a blank message is not. The message should be
> something like:
> "Parameter com.example.components.Layout.section is primitive type int and
> may not be bound to null. You should convert this parameter to type
> java.lang.Integer."
> Possibly we could get some similar effect by automatically forcing allowNull
> to false for primitive type parameters.
