Call to a member function value() on a non-object

I have the same issue with the search_api_pages module. So it makes it completely useless. It worked before I updated everything to the new version, the version I was running was at least 8 months old but it worked.

Can you provide more information ? Your index configuration .... What are you trying to do exactly ...

I'm using the profile2 module to built an alumni database. I was using the search api to look in different fields of the profiles. I'm only using the dbsearch module. Since I updated I get the error message everytime I try to do a search. Indexing works fine. Of course my error does not come from the drush app but directly from the site. My index configuration is_

Some fields are checkboxes. But like I said, the indexing works fine. The problem appears when I try to do a search.

I get:
Fatal error: Call to a member function value() on a non-object in /website/sites/all/modules/search_api/search_api.module on line 1552
Do you need more info? Just let me know.

I don't think that's it, at least not in my case. I deleted all indexes and created them anew.

Mantainer needs more info? What more info do you require? Let me know and I will give it to you, gladly.

I take it you have tried with the latest devs (Search API, Entity API and Profile2)? Then please see if the attached patch fixes your problem.

Sadly it did not fix mine. Now my search results are not shown. The line for the results says I have results, but nothing is shown. The good thing is I don't get any errors anymore. But no fix.

Ran into this error just now myself. I have a fresh instance with an empty index. I was able to get to about 45% indexed via some cron runs before hitting the error. I've applied the patch and so far no more errors and indexing is continuing.

Ok, this also fixed it for me. So that's three cases where this fixes the issue.

Still, there seems to be something weird going on. This is my backtrace:

The issue was launched on a $wrapper for a field of type "long text". The field was defined on some node types, but I didn't had any node type with that field on the database.

Thanks for testing, and glad this worked for you.
Also, I'm very sorry I took so long to get back to you.
Anyways, committed.

@ reptilex: If you keep having problems with this, please open another issue and we'll try to get to the bottom of your problem.
