[Red5] All of a sudden no custom classes...?

k, switching back to 0.7.0 i fixed my problem...
i had restarted my machine - and red5 started up in the background, when i
started red5 in eclipse via the plugin somehow i must have had two instances
running - not sure how as i was getting no 'address already in use' - but i
think this was my problem.
so to send custom classes in 0.7.0 you don't need the IExternalizable
interface...
and you need the explicit/implicit getters/setters - so, client side, this
will work
private var test:Number;
private function setTest(value:Number):void
{
test = value;
}
private function getTest():Number
{
return test
}
or this will work:
private var _test:int;
private function set test(value:int):void
{
_test = value;
}
private function get test():int
{
return _test
}
and server side you'll need
private double l;
public double getL() {
return l;
}
public void setL(double l) {
this.l = l;
}
once i can get the trunk running i'll do a more thorough test and blog the
results with examples.
one final point is that it seems that all primitive types except String get
initialised to some default value. For instance if you don't initialise any
properties then Number will get returned as 0, Boolean as false... but
String comes back as null.... so maybe something to watch out for.
