One way that I have implemented this in our solo app is to use the
LzDelegate and LzTimer together. For instance:
[CODE]
<method name="startPoll">
this.pollDelegate = new LzDelegate( this, "pollServer" );
LzTimer.addTimer( this.pollDelegate, 1000 );
</method>
<method name="pollServer">
canvas.checkSession(); // checks if session is still valid
board.updateBoard(srv.boardname); // updates the board dataset
LzTimer.resetTimer( this.pollDelegate, 1000 );
</method>
[/CODE]
So in this case the my dataset is called "board" and the "updateBoard()"
method just makes the dataset request the data from the source again.
This is how the boards on http://www.clockthat.com get updated
"globally" so that all users can see updated boards.
HTH,
Adeola.

No problem.
FYI: The startPoll() method is called in the canvas's oninit event:
<canvas ... oninit="this.startPoll()">
...
</canvas>

Subject: [Laszlo-user] About refreshing data
To: [email protected]
Message-ID:
<[EMAIL PROTECTED]>
Content-Type: text/plain; charset="utf-8"
In a old post, i've asked if it's possible to refresh data on a client
program when another client program is modifying database table n_uplets.
I've been searching trhough www.osflash.org and saw Red 5 (
www.osflash.org/red5), a flash server with functions like Flex's future
Adobe comms. server.
I think it can do that. I'll send my progress there if nobody is against.
Thanks.

When you run it as a SOLO application on a webserver (non-proxied mode), you
only need to upload the one main SWF file along with any other resource
files that are loaded at runtime (ones that are not already compiled into
the SWF).
If you run it as a proxied application using the full OpenLaszlo server,
then you need to upload all the LZX files and all the resources your app
needs... JPG, SWF, GIF, PNG, XML, MP3, etc...

If you're only trying to update the client with data, you have a few
options besides Comm Server/Red5, which may be a bit heavy-handed.
Among them,
- Have your laszlo application poll for updates, every 10 seconds or
however long makes sense.
- Use the (currently unsupported by Laszlo) XMLSocket object
(ActionScript) to receive "update" events, and either have the new data
pushed in through the socket, or use that to trigger an update through
the normal data request channel.
I'm using the latter of the two on a project now, and it's working well-
it's light enough that I could switch to a polling method later on with
ease.
