[firebird-support] violation of PRIMARY or UNIQUE KEY constraint

[m_brahi...@yahoo.fr [firebird-support]]

Hi all,
 

 I get the  following message  when create and compiling a view under IBEXPERT :


  violation of PRIMARY or UNIQUE KEY constraint "RDB$INDEX_15" on table 
"RDB$RELATION_FIELDS".

 Problematic key value is ("RDB$FIELD_NAME" = 'COMMUNE_ID', "RDB$RELATION_NAME" 
= 'VW_EMPLOYE_FULL_LISTE').
 

 I am using FB3
 Can you please tell me from where it comes ?
