[jira] [Commented] (ISIS-1284) Fails to render a property with compile-time type of Object but returning a value type (eg joda DateTime).

    [ https://issues.apache.org/jira/browse/ISIS-1284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15072760#comment-15072760 ] 

Dan Haywood commented on ISIS-1284:
-----------------------------------

The problem seems to be the property defined as:

{code}
    public Object getRequest() {
        return new DateTime(start);
    }
{code}

This renders fine if defined as:
{code}
    public DateTime getRequestDT() {
        return new DateTime(start);
    }
{code}

and indeed this also renders:
{code}
    public Object getRequestDT() {
        return null;
    }
{code}

as does:
{code}
    public Object getRequestDT() {
        return this;
    }
{code}

However, I also triggered an error using:
{code}
    public Object getRequest() {
        return "foo";
    }
{code}

so I think the issue is that a compile-time type of Object indicates that a reference type will be returned, but then returning a value type such as a String or a DateTime triggers the issue.

Is there a particular reason why the compile time type was defined as Object in this case?
