Re: [weld-dev] Reattach to conversation
Hi Matej,
Thanks for the reply.
The cid is passed correctly via page forwards, we are trying to avoid
ever having it appear in the browser address bar because if a user
bookmarks it, it will crash on the following session due to an invalid
conversation ID.
The case I'm trying to solve here is how to stop a user refreshing the
page creating multiple new conversations which causes the package of
work to reload multiple times. Each package has a unique ID so the
mapper of conversation ID to this package ID seems a natural one for us.
For example, the URL already has a page.xhtml?packageId=123 on it which
allows us to (hopefully) bring them back to their current running
conversation if we can successfully reactivate it.
Regards,
James.

Hi James,
a conversation is identified by its ID and if it is already active, you should be adding
the 'cid' parameter with proper value to your requests[1].
This of course requires the conversation to be long-running which I assume you have.
Is this what you meant?
Matej
