My Map web app reads client list from SQL server and for each client it draw points on a different layer so that the user could turn on and off that layer and see his entire customers. Problem is that once I have around 80+ layer than popups are appearing below the layers. Is there a workaround how I can show different features and turn them on / off without screwing with the popups ?

You should have all those points in a single layer. And set the visibility for each feature instead of layer.

So... How do I associate the points to customers? so when I uncheck a customer , some points go visible = false; – Alophind Nov 13 '12 at 4:28

you need a filter on customer id (or something). See openlayers.org/dev/examples/cql-format.html for an example – iant♦ Nov 13 '12 at 8:36
You can also store the customerid in feature.attributes.customerid If the user unchecks a customer, loop through the features do visible = false if it is unchecked. – CaptDragon Nov 13 '12 at 16:32
Thanx Capt. Good idea. – Alophind Nov 14 '12 at 10:23
