Ok
I finally found a solution (not sure it's the easier solution but it's
working in all case
When declaring StyleMap I add this Rule:
new OpenLayers.Rule({
name : "changestate",
symbolizer: { "Polygon": { display : "none"} },
filter: new OpenLayers.Filter.FeatureId({fids :
[]})
})
So currently this has no impact, as the list of features id is empty.
Now, in my changestate function (this function is called when a feature
status must be changed : show/hide)
features = layer.features;
unactivelist = new Array(); // List of feature ids to hide
n = 0;
for(i=0;i<dtnode.parent.childList.length;i++) { // I am
using dynatree (tree with checkbox)
// if style is defined (no stylemap associated) normal
case, just style.display = "none"
if (features[i].style) {
if (dtnode.parent.childList[i].isSelected())
features[i].style.display = "block";
else
features[i].style.display = "none";
} else {
if (!dtnode.parent.childList[i].isSelected())//
checkbox not active so add to unactive
unactivelist[n++] = features[i].id;
}
}
}
//Get layer.stylemap.style.rules.filter and change fids to
the new list, redraw the layer
style = layer.styleMap.styles["default"];
for(j=0;j<style.rules.length;j++)
{
if (style.rules[j].name == 'changestate')
{
style.rules[j].filter.fids = unactivelist;
}
}
}
layer.redraw();
