[OpenLayers-Dev] Re: vector layer with highest zIndex not overlaying other vector layers

[crb]

Hi Andreas.  Thanks for the reply (and for the reply to my other post of the
same day).

The reason for the extra layer for the selected features is because we want
to show selected features at all scales, but the vector layer for our
"locations" layer has too many features to display at all scales:  it drags
IE to a crawl, rendering it unusable.  So for our "main", location features
layer, we display only at the 10th zoom level and we display only the
features within the maps current extent (requiring a callback to the server
every time the extent changes) and we use a cluster strategy for it.  This
helps with the locations layer (sort of -- I'll be posting again shortly in
another thread regarding problems we're having with the cluster strategy)
but so that the user can always see all the features that they've selected,
we need a 2nd vector layer (or equivalent) to display only selected features
at all scales.

Even given that, we've decided to hold off adding a 2nd selected features
layer for to make sure we can get the cluster strategy working the way we
need it first.  We'll likely revisit this, but we have to resolve our other
issue first...
