DXA Link resolver issue

Question

We have a Page with Component A (a container Component) associated with a static template which has another Component B as a Linked Component field. In the associated model for B, I have created a field to serve URL like:

@SemanticProperty("_self")
private String url; 

URL field is always empty, even if the Page containing parent Component A is published. There is a dynamic Component Template present for the Component B. Here is the diagram of page AB where B is present as a linked component:

I am mapping model for page CD where B is also present which has the url field with empty value:

Can anyone suggest if I am missing anything?

Answer 1

Despite your pictures, the structure of your View Models (and how they map to Components in CM) is not quite clear to me. For example: what does "Component as embedded field" mean? Do you mean you have an embedded View Model mapped to an embedded field?

Regardless, it seems to me you want to get a link to Component B resolved. DXA link resolving will resolve a Component link to a URL of a published Page which contains a Component Presentation for the linked Component.

In your description, I don't see that you have such a Page, which could explain why the link does not resolve.

In case Component B is a Multimedia Component, you may want to resolve a link to its published Binary content instead. In that case, you should make the property of type MediaItem (or a subclass).
