T5: pass value between components in different pages
I have two pages, list and edit pages. Each page contains one or more
components. From list page, I use an actionlink to pass the item id as Long
to edit page, which I have a setter to set this id in the component which I
like to use (in which I persist this passed id).
Everything is working well if you keep working between those two pages, but
I found one problem which is the id value will be null if I refresh the edit
page after like 10 min. the T5 will throw exception as follows:
org.springframework.transaction.UnexpectedRollbackException: Transaction
rolled back because it has been marked as rollback-only
To me it seems that the id value passed from list page has got lost/cleaned
up.
I have tried some alternatives, but no of them is working.
Any help will be appreciated!
David

Thanks for your suggestion.
Actually it is not caused by session timeout, because by default session
timeout is 30 min. In my case, I refresh page just after 10 min. I think the
way I was doing somehow the value/reference of value was cleared by T5.

Instead of persisting the id in the component, why not keep the id in
the page's context and pass it to the component as a @Parameter?
If you store stuff in the session then your component needs to be
smart about what to do when the @Persist'd object is null after a
session timeout.
