Several warnings and notices

I also get:
"Warning: Invalid argument supplied for foreach() in search_api_facets_paths_url_outbound_alter() (line 100 of /var/www/sites/all/modules/search_api_facets_paths/search_api_facets_paths.module).
Warning: Invalid argument supplied for foreach() in search_api_facets_paths_url_outbound_alter() (line 100 of /var/www/sites/all/modules/search_api_facets_paths/search_api_facets_paths.module)."

EDIT: Actually its way more than just that, depending on the search...

Applying that patch stops the warnings but then nothing happens when I click on a facet. The url is appended to but the search results are unaffected.

Added to 7.x.-1.4

As I said in #2 this only fixes the warnings.
The facets stop working though, and only append onto an ever-expanding url without ever actually filtering the results!!

Its just the taxonomy terms.

EDIT: This was a stupid post. No, really. Stupid.

Oh bugger - ignore #6 as its really just rubbish.
EDIT: I initially made a long-winded explanation of why I said what I said in #6 but it doesn't really matter and just confuses issues. The point is it was garbage and should be ignored. Sorry!

Back to the point now and I haven't got a clue why this isn't working then.

It only happens to Taxonomy >> Name facets - i.e. the ones that it is attempting to rewrite.
And it only happens on paths that it has been enabled for.

Trying to work out if there's anything else to it now...

EDIT: I thought I'd found out what was going on but I was wrong.
Blehhh.

EDIT: Wrongwrongwrong.

EDIT: Blah wrong issue >_<

...This is not going well for me.

Just seen your email Michael, I'll give you access to my test site and email the details.

Okay one thing I notice is that we're using different versions of Search API. For instance, the version I'm using uses Fulltext or String for taxonomy term names and has no special Taxonomy term field type. I can't see your version number so here's my list:

Search API	7.x-1.0-beta7
Search facets	7.x-1.0-beta7
...

It's all 7.x-1.0-beta7

Ah. I'm on the latest dev version.
Also, those special term fields are do to a patch that I forgot to rollback before giving you access - I assure you that the problem occurs even without it.

Hold on, I'll roll it back.

Okay it's not the version but more about your label issue. For Pretty Paths to work you need to use the Category >> Name facet. The ID based ones don't work. Probably should document this. Your Multi and Single test are working too - maybe because I ran the re-index from the Search API menu.

Awww crap. I'm gonna have to create a new index again. Hold on.

EDIT: Sorry, that was a cross-post. But that isn't right, the ID ones weren't what I was testing, they were for something else. It was the >> Name ones I have the problem with. One of them works (Tag) but the others don't.

And I'm in the process of rolling everything back to an earlier version, bear with me.

Here we go. Try again.
I'm now back on the beta7 version, no patches.
You should see what I see right away - the last facet block (Tags) works but the other 3 don't.

It's the space in the vocabulary name. I hadn't tested with that.

o_O

Phew.
That makes sense.
I figured there had to be something different between those 3 and the one that worked... Didn't twig that a space could be the cause.

Its a huge relief to have an answer - this was seriously bugging me!!

Thanks Michael

fixed in 7.x-1.6
