Fix build of lookup table for grouped ids

Gerry Vandermaesen · jmikola · commit c519f6d017c5 · 2014-04-29T15:33:56.000-04:00
The ODM allows the use of custom types for identifier fields, however it currently uses the PHP value of an identifier as an array index key for grouping IDs together. This throws errors when the PHP value is a non-scalar.
