[Red5devs] Serverside cast problems with remote shared objects

[Valentin Manthei]

Hi everybody.

I currently have some problems with handling my remote shared objects in
my webapp.

I save the rso attributes as an ArrayList but when I operated with them
sometimes (not frequently) ClassCastExceptions occurred.
-> java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast
to java.util.ArrayList

Some code snippets:
Adding an user:
ArrayList<String> vl = (ArrayList) viewerList.getAttribute("rso_name");
if(vl == null) {
   vl = new ArrayList<String>();
}
vl.add("username");

Removing an user:
ArrayList<String> vl = new ArrayList<String>();
vl = (ArrayList) viewerList.getAttribute("rso_name");
if(vl != null) {
    int listsize = vl.size();
    if(listsize > 0) {
        for(int i=0; i<listsize; i++) {
            if(vl.get(i).substring(0,
vl.get(i).indexOf("/")).equals(viewer)) {
                vl.remove(i);
                break;
            }
        }
    }
    viewerList.beginUpdate();
    viewerList.setAttribute(broadcaster, vl);
    viewerList.endUpdate();
}

I also experimented with storing the rso data in a HashMap but in this
case he told me the cast from ArrayList to HashMap cannot be done. What
the hell? ;-)

Im not sure if thats a red5 or a Java problem, but i hope someone can
help me out of it.

Best regards,
Valentin
