[GENERAL] Views permision -- please help and suggestion

[salah jubeh]

I have two views A and B such that A depend on B. Both of them has the same 
permissions.  


when I excute 

SELECT * FROM  A;

ERROR:  permission denied for relation B

********** Error **********

ERROR: permission denied for relation B
SQL state: 42501


However, I can do 

SELECT * FROM  B;

How can I trace this problem, It really confuses me. 

Regards
