D5 IW 8.022 I am trying to build a database app using IW. It was connecting to the database and I could access data. But I tried to put in code to upgrade the tables if needed. The upgrade functions are in another unit and I call them from IWUserSessionBaseCreate. In the upgrade functions the table references are prefixed with TIWUserSession(WebApplication.Data). The problem is when the update functions are called WebApplication.Data = nil so I get an AV. Why would WebApplication.Data = nil?

The problem is when the update functions are called WebApplication.Data = nil so I get an AV. Why would WebApplication.Data = nil? Because it hasn't yet been assigned. But, if I understand your layout, webApplication.Data would be the same as Self in the IWUserSession's create handler, you can just pass Self to the functions.
