Hi all, I have a question about whether it's possible to access RequestVars in CometActors (specifically, to access them in localSetup). I believe it is, based upon a recent thread about sharing them among snippets[1] and an older thread about Actors accessing S[2]. But first, some background, as I may be going around this in totally the wrong way and would appreciate your thoughts.
I am making a dashboard to display a bunch of data that will be coming in (near) real-time and I want to use Comet to make sure the user always sees the most update-to-date information in their dashboard. I have a variety of different aggregate values to display that fall into several categories together, so I can group the calculations together. I think this sectioning will prove useful in the future, as I can imagine wanting to display some but not all of these sections on another page. Because the CometActors all will need to know the dashboard to which they belong, my thought was to share this Mapper instance via a RequestVar. I call my snippet like so: <lift:Dashboard.display> </lift:Dashboard.display> The snippet defines a RequestVar called myDashboard and then returns a NodeSeq: <div> <lift:comet type="DashboardHelper1"> </lift:comet> // .... <lift:comet type="DashboardHelperN"> </lift:comet> </div> While I can get this all to compile, myDashboard is empty in the CometActors. I understand that CometActors basically exist outside of the normal request cycle, so would this be the reason why my RequestVar is always empty? I was hoping that it would still be in the request cycle when localSetup is called, but I can see why that would be unrealistic. I just tried using SessionVar instead of a RequestVar and this works. However, I'm worried about having to be more careful about emptying the SessionVar if requesting a different dashboard than if I would if I were using a RequestVar. Is this an unrealistic fear? What do you think is the best way to proceed?
