When I'm submitting the creation form to create a new index of any of the denormalized item types I get the following error:

Fatal error: Unsupported operand types in /var/www/oam6/sites/all/modules/search_api_grouping/includes/datasource_denormalized_entity.inc on line 248 Call Stack:

Syslog provides more precise information:

Warning: array_fill(): Number of elements must be positive in SearchApiDenormalizedEntityDataSourceController->createPermutationItems() (line 248 of .../sites/all/modules/search_api_grouping/includes/datasource_denormalized_entity.inc).

and

Warning: array_combine() expects parameter 2 to be array, boolean given in SearchApiDenormalizedEntityDataSourceController->createPermutationItems() (line 248 of .../sites/all/modules/search_api_grouping/includes/datasource_denormalized_entity.inc).

Clearly count($ids) is 0.

This can be traced back to the fact that $denormalization_fields is empty on line 247.
$denormalization_fields is initialized on line 241.
It is initialized to an empty array because there are no processors on the index.

I'm using drupal-7.22, search_api-7.x-1.6, search_api_solr-7.x-1.1 and search_api_grouping-7.x-2.0-beta1.
So according to me the patches are installed. (Btw the part about the patches is very confusing.)
I'm perfectly well able to create an index on any of the non-denormalized item types.

I patched the code a little bit, so I was able to actually create the index and configure it.
Initially I was not able to index the items because there were no items to be indexed.
After setting "the fields to use to denormalize the items to index" there were items to be indexed.
It seems that during creation of the index "the fields to use to denormalize the items to index" are queried and used to determine the items to be indexed.
Since there are no fields yet it will fail as described in the issue.

It should not be to difficult to write a patch for this.

Hi,

I was seeing the same issue. Did you get it all working? I manually patched the offending code (it was trying to loop on normalized fields which haven't been set up at this stage) but still had trouble getting any of the functionality working correctly.

Thanks.

Hmm, I'm not sure if I fully get the issue - and it would be nice to know what you've patched to get it working. Since it seems that your adjustments worked out.
However, I've pushed a change to avoid the error: http://drupalcode.org/project/search_api_grouping.git/commitdiff/974c8b3...

Let me know if this makes any difference.

Please see the attached patch made against 7.x-2.0-beta1 to address (refresh?) comment #3 above which, when #3 linked patch was applied gave a gigantic screenful of debilitated pink for the db_update (see attached). Once applied, I was able to create the new index-- haven't tried beyond that yet :) Note: all this patch does is wrap to check for items to be thrown into db_update which, when empty, throws a bit fat PDO exception.

Patch attached.
