MSS iView Personalization

Friends,

We are not able to do Implicit Personalization for MSS iViews/Pages .When we open the iView in preview mode and set the property of a field to invisble mode then click apply and OK the filed gets hidded.But when we open or refresh that iView the field appears again in that iview.So please help in resolving this issue.We are using EP7.0 SP09 with MSS BP1.0 and Self service components 600 SP09.

Regards,

Arun
