Thanks for the fast reply Thiago!
I have tried to set this up in my Module class:
public static void bind(ServiceBinder binder)
{
binder.bind(SiteLinkFactory.class).withId("SiteLinkFactory");
}
public static void contributeAlias(
Configuration<AliasContribution> configuration,
@Local SiteLinkFactory siteLinkFactory)
{
configuration.add(AliasContribution.create(LinkFactory.class,
siteLinkFactory));
}
But I get a recursion exception when trying to load the web app. This type
of issue seems fairly common on the mailing list, but I've not found a
solution which works here yet.
As a baseline I've tried to create an alias for the LinkFactoryImpl class
instead of my own, but I get the same issue.
This seems to imply there is some dependency in the implementation of the
LinkFactoryImpl class which has a circular reference?
The LinkFactoryImpl takes these as arguments to its constructor, might one
be the issue?
Request request, Response response,
RequestSecurityManager requestSecurityManager,
RequestPathOptimizer optimizer, PersistentLocale persistentLocale,
RequestPageCache requestPageCache,
ContextValueEncoder valueEncoder, URLEncoder urlEncoder
Any thoughts on if I'm doing something wrong in setting up this alias, or a
way to work around this seemingly circular reference?
The exception:
