EntityMetadataWrapperException: Unable to get the data property field_languages_level as the parent data structure is not set. in EntityStructureWrapper->getPropertyValue() (line 396 of /var/www/fago/web/recruiter/profiles/recruiter/modules/entity/includes/entity.wrapper.inc).

Probably Search API should just catch that exception.

Since the error doesn't occur here: could you tell me, where in the Search API the exception occurs? In search_api_extract_fields(), which does the heavy lifting for extracting the data from the indexed items, all exceptions should be caught.

Yep, it still appears. I tracked it down to search_api_extract_fields(). The tricky thing is it appears when iterating over a wrapper, as iterating over a list needs to fetch the values to determine the keys, it can cause an exception. So best, just catch the EntityMetadataWrapperException for the whole function.

Probably we should always return an array though.

hm, that patch caused troubles when some values where empty. Improved variant attached.

Thanks for the patch!
Just to clarify: the error occurs when the given $wrapper is of a list type, but with NULL (or another non-array) as the value? Or when it is a list with a somehow faulty or inaccessible element?

I think it occurs if the value for the list itself cannot be loaded, thus causing an exception directly in

foreach ($list_wrapper as $item)

OK, then there really doesn't seem to be anything else we can do.
Committed your last patch, thanks again!
