Using Private Views in Lotus Notes has always been a bit of a double edge sword.
They do have their obvious benefits and can work fantastically. Unfortunately they have their limitations, which on paper would be quite easily resolved with a little work.
The problem I have (like so many others I'm sure) is that when a design change is made to the Parent View there is no real straight forward way to get the users private view to inherit this change.
It has always been a bit of a hack around to get the Db icon removed from the workspace thus deleting the users private view, then a fresh Private View is created on next bookmark & open.
The other way is to change to Name of the Parent - again a real lame method as this just leaves redundant views.
I have found some work around LS codes although these again have their issues, and yes I have tried the @updateViewDesign which does not seem to do what it says on the tin.
So I hope this issue could be looked at one day, and I'm sure that it will only encourage the use of Private Views which I know Developers do avoid using due to these limitations in design change.
