I have a package with some Application Pages (in Layouts Folder) and a Feature which contains some WebParts. I tought the Layouts contents are copied first to SharePoint, then the WebParts from the Feature and then the Feature Receiver fires. At least it Looks like it in Visual Studio because the Layouts Folder is always at the topmost postition. But when I try to modify the Pages in the Feature Receiver it throws an file does not exist Exception. The Urls are correct and if I modify an existing Page it also works.
What do I have to do to have my Receiver firing after all the Layouts content is deployed?
