    Opened a support ticket and this ended up being an issue with the browser and the F5 admin page. Deleted all cookies, restarted the browser and entered the expression again and it no longer garbled the expression as it had previously. The expression is now working fine.

Hi

I shouldn't think performing a Variable Assign to an expression would be possible. Expression is meant to produce a result, not a variable.

The correct expression for what I think you're trying to do would be something like...

session.logon.last.username = Session Variable session.saml.last.identity

You shouldn't need to use an expression to obtain that variable though. Also that expression is incomplete/invalid (see the log entry) so I'm surprised its worked for you in the past (maybe older version?) I suggest you try the variable assignment I mentioned or using the simple view Lucas mentioned.
