[Users] Openlayers 2.11 and Map tabs

[Dan Ramage]

Ah, I was wondering if that might be the cause.
I ended up having to set deferredRender: false on all the panels that made
up a tab, as well as the tabPanel.

Thanks for the suggestion!

Oh sorry, I just saw that we're on the GeoExt list here, and not
OpenLayers. I seem to remember that I was able to solve this by
configuring the TabPanel with

deferredRender: false

Minimal example:

new Ext.TabPanel({
    deferredRender: false,
    width: 600,
    height: 400,
    renderTo: document.body,
    activeTab: 0,
    items: [{
        xtype: "gx_mappanel",
        title: "map 1",
        layers: [new OpenLayers.Layer.OSM()],
        center: [0,0],
        zoom: 1
    }, {
        xtype: "gx_mappanel",
        title: "map 2",
        layers: [new OpenLayers.Layer.WMS("wms",
"http://demo.opengeo.org/geoserver/wms", {layers: "world"})],
        center: [0,0],
        zoom: 1
    }]
});
