Views permision -- please help and suggestion

[salah jubeh <s_jubeh@xxxxxxxxx>]

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
