Maximum view state size limit exceeded

Stephen… that doesn’t seem to work. Below is the very simple code that is being used and I still get the error after adding the Readonly piece.

 ```

I also thought it may be due to the number of blank lines (there is a blank line between each row in the csv) and I took those out but increased the number of rows to about 5,000 and now I am getting the following error...

Apex CPU time limit exceeded
Error is in expression '{!validateFile}' in component  in page skuid:import: (skuid)

We (OpenGate) are a partner of yours (Skuid) so I don't see a need to get my Salesforce Admin involved.  I have already had this issue looked at by our developers here and I was hoping this was something you could help me with.

Please advise on what you recommend to try next.
