How do you force instances with the same name on the same layer to update?

Question

Maybe someone can tell me why flash doesn’t redraw
components’ x,y positions if they have the same instance name
and are on adjacent frames? (movieclips work fine, just not
components) If I have a button on frame 1 and a button on frame 2
both with the same instance name but different locations on the
stage, frame 2’s button doesn’t show up in the position
I placed it, it stays at the position of frame 1 but still has the
properties of frame 2’s button. The label changes and
everything. If I stick a button on a frame in between and give it a
different instance name there is no problem. I thought it might be
the style manager bug

but it didn’t seem to affect. This happens for textareas too
and probably all components although I haven’t tried them.
I’ve tried using drawNow() and validateNow() with no luck
either

Thank you!
// put this on frame 1 along with a button on the stage with
instance name: b
function doit(event) {
if (currentFrame == 1)
gotoAndStop(2);
else
gotoAndStop(1);
b.addEventListener(MouseEvent.CLICK, doit);
stop();
// put another button on frame 2 along with this code and
also make it’s instance name: b but move it so it’s not
in the same x,y coordinates as the button on frame 1
stop();
Something possibly related. I have a movieclip on a layer,
one instance with name “a” on frame 1 and one instance
with name “a” on frame 2 and it has event listeners
inside it that update something on the movieclip. Unless I put the
movieclips on separate layers the event listeners won’t reset
each frame. (example: a button with a tooltip onmouseover that you
want to change the text of from frame 1 to frame 2) You’d
think if they were on separate keyframes at least but no, they need
to be on separate layers too.
I want the movieclip to update each frame. Any ideas?

Answer 1

instances (whether components or not) with the same name may
or may not be the same instance. it depends upon how they were
created.
for example, if you create an instance on frame 1 of your
main timeline, give it an instance name and then create a keyframe
on frame 2, the two instances will be the same.
but if you create an instance on frame 1 of your main
timeline, give it an instance name and then create a blank keyframe
on frame2 and create another, what you think is a duplicate,
instance and give it the same name, it will be a different
instance.
