Facet API dependencies not working

Hmm, I wonder if it's just a missing UI element or whether it's not supported at all.

Has anyone found a solution for this?
I also have this problem. I am using 7.x-1.9.
In my solr shema, I have date fields and long fields.
Facets based on the date fields have the "Configure dependencies" contextual links, but I don't see the link for facets of long fields.
Here is what I tried:

- Changing my field types from long to integer, refreshed the sarnia properties,
- Changing fields types via hook_search_api_index_load, hook_entity_property_info_alter and hook_entity_load
- Set Query Type to term.

The only difference I see between date types and long types for the facet is the query. Date don't have a Query Type settings. Long or Integer do have Query Type set to sarnia_term. I suspect that this is related to the build function in the SarniaFacetapiTerm class.

Any help with this would be greatly appreciated.

I added the default Facet API plugins into the build array that generates the facets within Sarnia with the attached patch. Give this a try.

The following patch attached to this message may be a bit more useful: If the Facet API Bonus module is included and active, the dependency "Another facet" is made available.

#4 works like a charm. Thank you very much. I had managed to make it work by creating a "Facet dependency" visibility rules and adding the facets in panels but I had to remove the querystring params for hidden facets via url_inbound_alter() which was a pain.

This change committed in Sarnia-7.x-1.10 From patch #4

As it cycles though the 'bundle', 'role', 'facet' (it blows up on 'facet') and breaks all my Sarnia views.

It does work only if you have facetapi_bonus installed. I tested this out.
Simply downloading facetapi_bonus and turning it on makes it all fine.
I assume everyone (but me) was using this module, but it shouldn't be required - else it needs to be a dependancy.

It probably was not a wise assumption to make that the Facet API Bonus module would be active. I also thought that the default dependency on another bundle was not very useful, and that the dependency on another facet (which facetapi_bonus provides) would be.

Here is another patch testing for whether or not facetapi_bonus is activated.
