First of all I must say I am new to sharepoint. I have a problem that keeps recurring for me, and I have no idea as to why.
I have a list-view (or several really on different site collections) that originally has a number of columns. Lets say 5 columns. I have to remove 2 of these, and I do this by clicking "Modify view" and deselecting the columns. Returning to my view now, the two columns I deselected are now gone. I edit the webpart showing the list and make sure that it points to my newly modified view. I make sure that the columns are erased from my templates, and everything is looking as it should from my point of view.
Until the customer logs in - for some reason the changes I did to the list view is reverted back to its original settings. I have tried many things now, even a new deploy with the new settings (I can't delete and redeploy the whole thing as it has much data in it). I can't for the life of me figure out why this is happening. It is not a single incident either, as I have made changes over and over, and yet every time this particular user logs in, the changes are undone.
Any help is appreciated.
