T5: persist a list

[Angelo Chen <an...@yahoo.com.hk>]

Hi,

I got a list for a loop:

@Persist("flash")
private List<String> files;

Questions:

1. do i have to files = new List<String>() in my page constructor?
2. why this files never got empty, I can see it even from another browser?
how to empty this list?

Thanks,

A.C.

@Persist("flash") removes the object from the session after it reads it
while the page request is being prepared. Every time you set the value it
gets put back into the session. So, you could keep a flash persisted object
in the session perpetually if it's set from within your events or lifecycle
methods.

If you type Ctrl-N from IE you get a new browser window that shares the
session with the original window. You can try opening a different browser
(Firefox, Safari).

Hope that helps,
