3.2.5 java.lang.IndexOutOfBoundsException: Inconsistency detected

[AllanWang]

About this issue

(Similar report at #602 (fixed))

The implemented diff callback checks if items are the same using the identifier. This works fine, but if I set the comparator to check for the identifier, I get an OOB exception. The log is very similar to #602

To give more context, my adapter currently cycles through 2 item types. For one of them, the identifier works fine, whereas the other has inconsistent identifiers (which is why I wanted to use types). If I simply override that item creation to set the identifier to the hash of its data model and continue comparing by identifier, everything works fine. However, this moreso emulates the areContentsTheSame method. Is there something I'm not understanding here as to why comparing by type doesn't work?

The identifier must be unique inside an adapter. Two items can't have the same identifier even when there type id is different.
