Re: T5: How to handle caching for applications in multi-user environments

[Robert Zeigler <ro...@scazdl.org>]

Hi Thomas,

I don't have any issues in T5 like what you describe.

How are you storing the request values? I assume you're putting them  
into page fields?

A few things to check:
1) Your page fields need to be private
2) If you're trying to store the values in the httpsession, make sure  
you're using the @Persist annotation, rather than the @Retain  
annotation.
