Cannot filter != or NOT IN

[LevEricCheung]

I am a little new at this but I'm trying to find out why when filtering using != (and NOT IN) does not work, all the other operators (=, >, >=, <, <=) seem to work fine.

It throws an error when querying on GET on my server:

/api/ticket?filter[ticket_number][value]=220080&filter[ticket_number][operator]="!="

{
"type": "http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.5.1",
"title": "SQLSTATE[42S22]: Column not found: 1054 Unknown column 'node.entity_id' in 'where clause'",
"status": 500
}

Ticket is a node.
A Ticket__1_0.php was created that extends resourceNode
Ticket number is a field created with Field API.
Data provider is pointing to DataProviderEntity.

If anyone can help steer me in the right direction on where to look to fix the problem, it would be appreciated!

#1051 is merged and seems to solve your issue as well.
