Subject: [PATCH 1/3] Change comparison operator for array of id's

When there's an array of ID's present it looks like the Content Manager uses the '=' comparison which ends up returning an empty set. I think maybe the issue lies with the Content Manager plugin in that it should be using a 'IN' comparison if it detects an array. This is a workaround that seems to fix the issue. Although I'll be honest, I don't have enough knowledge of this plugin or the system to know if this will work for all edge cases.
