Hi List,<br>
<br>
i got this problem. Im trying dynamically change min and maxscale for<br>
layers. So for start i set maxScale=100000.<br>
var layer = new o.Layer.WMS(name, url, {params},{...maxScale:100000,<br>
minScale:500000});<br>
<br>
Then i add value 150000<br>
<br>
/*button onclick event*/<br>
layer.maxScale = document.getElementById("maxScale_value").value; //150000;<br>
<br>
OK , everything works fine. I can see layer from scale 500K to scale 150K.<br>
But when i change the value less then maxScale. for example to 50 000, it<br>
doesnt work. i can see layer from 500K to 100K.<br>
<br>
Then i tried something like this:<br>
var layer = new o.Layer.WMS(name, url, {params}); // without max/minScale<br>
<br>
map.events.register("move", map, function(){<br>
if(layer.maxScale == 500) // this is the default maxScale value<br>
{<br>
layer.maxScale = 100000;<br>
layer.minScale = 500000;<br>
}<br>
})<br>
<br>
and then the same button click event<br>
<br>
layer.maxScale = document.getElementById("maxScale_value").value; //50000;<br>
<br>
That is working for me. But there is another new problem. If i have layer in<br>
scales from 100000 to 500000 and i zoom to scale 525000 i cant see the layer<br>
(that's good), but when i launch browser console (F12), in Network list i<br>
can see, that the layer is still loaded in background.<br>
<br>
Any idea how to avoid this problem?<br>
<br>
Best regards.<br>
<br>
<br>
<br>
