LoadableDetachableModel sets attached true even when exception occurs during

-----------------------------------------------------------------------------------
Key: WICKET-2370
URL: https://issues.apache.org/jira/browse/WICKET-2370
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4-RC7
Reporter: Antony Stubbs
LoadableDetachableModel sets attached true even when exception occurs during
load(). We rely on exceptions being thrown / caught for our caching system,
which in this case sits behind our LDM. Problem occurs on 2nd load attempt
(where cache would now be populated), LDM returns null because the attached
flag is still true.
<code>
public T getObject()
{
if (!attached)
{
attached = true;
transientModelObject = load();
</code>
Locally, I will solve this for us by overriding getObject in a custom LDM which
will either reorder the calls i.e.
transientModelObject = load();
attached = true;
or, catch the caching exception and set attached to false.
I admit this is debatable behaviour though. Thoughts?
