Hi Tony,
I would add both lists to the layer's OMGraphicList, and then maintain
a handle on each set. Then, set visibility on either list as needed.
You might need to call generate() and repaint() on your layer after
the change.
But if they are large lists and you want to keep things the way they
are and minimizing the number of OMGraphics on the main list, trying
calling generate(projection) on the newly visible list and repaint()
after that. That might explain the problem where you can't see either
list.
For seeing both lists, I would check what you are doing in your
prepare() method, reacting to projection changes of the map. My guess
is that something is happening there where both lists get added at the
same time with visibility set to true.
If you want to send me your layer code I'll take a quick look at it.
Hope this helps,
Don
