I am not been able to update any of the attributes in one of my feature classes using the Arc FM Attribute 
editor, but I am able to update it thru the ESRI Attribute 
editor. 
Please lemme know if somebody knows the reason. 
I am using Arc SDE 9.3.1 with ArcFM 9.3 and ArcMap 9.3 
Note:I am in selection Tab and not in Target tab.
Please let me know if sombody can figure out the reason.
