Jochen Kemnade created TAP5-2495:
------------------------------------
Summary: NullPointerException in EnumSelectModel for invalid
Property
Key: TAP5-2495
URL: https://issues.apache.org/jira/browse/TAP5-2495
Project: Tapestry 5
Issue Type: Bug
Reporter: 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}}.
