hi all,
Some pbs with Strategy.Refresh :
Imagine the following layer :
var layer = new OpenLayers.Layer.Vector("FIR+Sigmets", {
strategies : [ new OpenLayers.Strategy.BBOX()
,new OpenLayers.Strategy.Refresh(
{force: true, interval: 10000 } )] ,
protocol : new OpenLayers.Protocol.HTTP( {
url : "./xml/data.xml",
params: { 'key': Math.random()},
format : myformat
}),
styleMap : new OpenLayers.StyleMap(style),
renderers : [ "Canvas", "SVG", "VML" ],
projection : map.displayProjection
});
I noticed *2 pbs :
1/ If i add a control select : selectControl = new
OpenLayers.Control.SelectFeature(layer), with an open popup on feature
selection. The pb is that when the layer is refreshed, the popups are
not erased...The layer changed, and it is not possible to access to the
layer used to create popup...
2/ In the example, note that the url of protocol.HTTP includes a
Math.random() key. Refresh process does not seem to generate again the
key param...
any help during this hot summer ?
