I have a multi application system with a custom authentication scheme, all working perfectly since Apex 3.2
After updating a test site from 4.1.0.00.32 to 4.2.0.00.27, I have noticed the following issue;
A standard button with an Action set as "Redirect to URL", with a "URL Target" similar to "f?p=CC:40:&SESSION." no longer generates a checksum, which is required by the target page.
The application with the button is different to the target application, both are in the same workspace
I seem to recall something similar being posted before, long before 4.2 though, but I have not been able to find it.
Is this a change in functionality (nothing in the release notes) or a new "feature" -;)
