Hello, 
I create a new custom model in Portal. With user Administrator i've no problem (good ^^), but with a specific user "test" of specific groups "Commercial Partenaire", i've this error :  

AccessError
...
(Type de document: ir.filters, Opération: read) 
 

I try to define access right and/or record rule in model ir.filters. But nothing work !
This error appear just when i update a record (not in create). When i active debug mode in eclipse, this error is raise in return res of my function write().


Someone can help me ?
