I am trying to create a custom default view for a list. I made a copy of my list's AllItems.aspx page, and renamed it, and inserted a CEWP onto the page, as I would like to use jQuery to display a color in a column field similar to http://www.sharepointkings.com/2009/04/sharepoint-calculated-column-and-jquery.html. The issue I am having is that when I save my changes and check in the new page, SharePoint removes all of the web parts that were on my page.
Why is this happening, and how do I stop it from removing my webparts?
UPDATE: Still not definitely sure why, but I noted that it stopped doing this when I changed the filename to something different, instead of the default copied filename which I had been using before.
