#28053 — Applet instances

If you have multiple instances of an Applet on page, how can they give
error messages to tell you which one is having a problem.  I have 
added <parameter name="instance" value="10"> with unique values to
each instance.

Is there an easier way?

I thought there was but looking at my code (which I hope to finish over 
easter) I just use static variables and an array of my <windowSlot> 
class. If there's a null entry use that else .add() it on the ArrayList etc.

I'll check again next w/e 'cos iirc the Applet thread gets a unique 
index for each instance so I'm guessing there's some intrinsic attribute 
somewhere.

with the old APPLET tag there was name=. I think it has disappeared in
HTML5 OBJECT. Logically ID= should work, but I don't think there is a
method to read it.

In my case, I generate the OBJECT tags with a macro generator, so it
is no problem to add a sequence number on page parameter to uniquely
identify applets.

<param name="instance" value="12">

I suspect that using static for communication will have the same
problem.  If the browser starts putting your Applets in different
JVMs, they will each get their own static area.
