[a4j] poll+actionparam

mail.micke Dec 13, 2007 7:27 AM

Hi all

Can I use actionparam or f:param with the poll component?

I've done some experimentation which indicates that I can't, can I?

What I want to achieve is to have a request scoped backing bean that will fetch data for a certain id wich it initially gets as a request paramter.
When polling the page I need to keep the value for that id somehow.

Currently I have it working by using a4j:keepAlive and an action method that refreshes the data based on the id, but would much rather just pass the id as a parameter.

Thanks,
Mike

What I was thinking about (and tried) is something like this:

<a4j:poll ....> <a4j:acctionparam .../> </a4j:poll>

My test didn't work, sometimes it seemd to work for the first couple of polls but I'm not sure.

Is it suppose to work, then I'll give it another go and properly check what is going on.
