TAP5-2495: Report an error if an EnumSelectModel is created for property
conduit that does not return an enum type.
> NullPointerException in EnumSelectModel for invalid PropertyModel
> -----------------------------------------------------------------
>
> 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}}.
