>                 Key: TAP5-2495
>                 URL: https://issues.apache.org/jira/browse/TAP5-2495
>             Project: Tapestry 5
>          Issue Type: Bug
>            Reporter: Jochen Kemnade
>            Assignee: Jochen Kemnade
>
> This can be reproduced with the following code snippet:
> {code}
>     Class c = String.class;
>     new EnumSelectModel(c, new MapMessages(Locale.US, Collections.emptyMap()));
> {code}
> It happens in {{org.apache.tapestry5.corelib.pages.PropertyEditBlocks.getSelectModelForProperty()}} if a {{PropertyModel}} has an {{enum}} datatype but the {{PropertyConduit}} returns a non-enum class from its {{getPropertyType()}} method.
> Of course, that's a user error, but we should be nice and report a better exception.
> There should be checks in {{EnumSelectModel}} as well as in {{PropertyEditBlocks}}.
