+ * Ensure that multiselect boxes have trailing brackets in their 'id' and 'name' attributes.
+ *
+ * These brackets are required for an array of values to be sent in the POST
+ * request. Previously, bp_get_the_profile_field_input_name() contained the
+ * necessary logic, but since BP 2.0 that logic has been moved into
+ * BP_XProfile_Field_Type_Multiselectbox. Since bp-default does not use the
+ * BP_XProfile_Field_Type classes to build its markup, it did not inherit
+ * the brackets from their new location. Thus this workaround.
