Hello all,<div><br></div><div>Just an update to the problems i was having.</div><div>Regarding the problem with layer ordering it was a programmatic mistake because i was using setLayerZindex method instead of setLayerIndex. Changing to this method solved the issue.</div>
<div><br></div><div>Regarding printing with legends but removing the vector layers from the request, i was able to achieve this, but not through an elegant way. Nevertheless it works. I created a fake GeoExt.LegendPanel and i remove the vector from this panel instead of the main panel through the following:</div>
<div><br></div><div>var legendPanel = new GeoExt.LegendPanel(...); //my main legend panel</div><div><br></div><div><div>var cloneLegLayerStore = new GeoExt.data.LayerStore();</div><div>var cloneLegPanel = new GeoExt.LegendPanel({</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>layerStore: cloneLegLayerStore</div><div>});</div></div><div><br></div><div>then, in the print button handler i do:</div><div><br></div><div><div>var legLayers = legendPanel.layerStore;</div>
<div>var cloneLegLayers = new Array();</div><div>legLayers.each(function(record){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>var layerRec = record.get('layer');</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>if (layerRec.CLASS_NAME == 'OpenLayers.Layer.WMS'){</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>cloneLegLayers.push(record);</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>}</div><div>});</div><div>cloneLegLayerStore.add(cloneLegLayers);</div>
<div><br></div><div>And with this, only my WMS layers legends are being printed.</div><div><br></div><div>Thanks a lot for all the comments and help, Geoffrey and Christian.</div><div>Cheers,</div><div><br></div><div>Hugo</div>

I would say, your legendPanel is not really cloned. In fact, the same javascript object relies upon your both variables ("legendPanel" and "cloneLegPanel"). It may exist a way allowing to really copy a javascript object and "paste" it in an other variable. In your case, it subsists a link between your two variables: when you modify the object represented by one of them, it also affects the other. Unfortunately, I don't know how to solve this problem. For layers, in GeoExt, it exists a "clone" function for the "LayerRecord" class that cleanly clones layers. It might be possible to do something similar with your legend.<br>
<br>
An other idea: if it doesn't work with the "beforeprint" function, you can try the "beforeencodelayer" function. In my app, I use this function to change layers url before they are printed (because of some problem with GeoWebCache layers). It works for layers: maybe there is a way to use this function for legend?<br>

Hi,<br>
<br>
After testing a little bit more, i found that if i use this code in the<br>
beforeprint listener it still complains about the encoding itself. So, i<br>
moved this code to the handler of a print button before calling the print<br>
method. Using this approach it works somehow but it removes all my vector<br>
layers from the map. As you told, i have cloned the legendPanel (using<br>
Ext.apply) and still get the same issue, all my vector layers are gone.<br>
<br>
Here is the current code:<br>
<br>
var cloneLegPanel = {};<br>
Ext.apply(cloneLegPanel, legendPanel);<br>
var legLayerStore = cloneLegPanel.layerStore;<br>
legLayerStore.each(function(<u></u>record){<br>
var layerRec = record.get('layer');<br>
if (layerRec.CLASS_NAME == 'OpenLayers.Layer.Vector'){<br>
legLayerStore.remove(record);<br>
}<br>
});<br>
printProvider.print(mapPanel, printPage, {legend: cloneLegPanel});<br>
<br>
With this code i get the legends in the mapfish print pdf but i cannot print<br>
vector layers and they are removed from the map.<br>
What would you suggest? The thing i don't understand is why my vectors<br>
layers are being removed when i'm using a cloned object of the GeoExt Legend<br>
Panel. Any ideas?<br>
<br>
Thanks once again,<br>
Hugo<br>

Hum, looking at your code, it might work! What does it happen with this<br>
code? Vector layers are completely removed from the map, not only from the<br>
legend panel? In this case, you should indeed clone your legend. Then, you<br>
could remove vector layers from this cloned legend. A the end, you can<br>
replace the old legend by the new one in your print function.<br>
<br>
I have never gone into this problem, so I have no ready-made solution! In<br>
my app, I have deactivated the "print legend" capabilities when a vector<br>
layer is contained in a map.<br>

Thanks a lot for your comments but my problem is exactly at destroying the<br>
legend printing for the vector layers. I have no idea on how to do this. I<br>
have tried the following but without success:<br>
<br>
beforeprint: function(printProv, printMap, printPages, printOpt){<br></div></div>
var includeLegend = Ext.getCmp('includeleg').**<u></u>getValue();<div class="im"><br>
if (includeLegend == true){<br>
var legOpt = printOpt.legend;<br>
var legLayerStore = legOpt.layerStore;<br></div>
legLayerStore.each(function(**<u></u>layerRec){<div class="im"><br>
var layerDef = layerRec.get('layer');<br>
if (layerDef.ClASS_NAME == 'OpenLayers.Layer.Vector'){<br></div>
legLayerStore.remove(layerRec)<u></u>**;<div><div></div><div class="h5"><br>
}<br>
})<br>
}<br>
}<br>
<br>
So my question would be, how can i tell the printprovider to not print the<br>
legend for this type of layers?<br>
<br>
Thanks a lot,<br>

I would rather use the "beforeprint" or the "beforeencodelayer" function<br>
from the "printProvider" class. This function allows you to change some<br>
parameters before layers are printed. So, trough this function, you can<br>
test if your map contains vector layers. In this case, you can probably<br>
find a way to destroy their relative legend from the print process. You<br>
will find below an example:<br>
<br>
printProvider = new GeoExt.data.PrintProvider({<br>
method: 'POST', // 'POST' recommended for production use<br>
('GET' for<br>
development)<br>
capabilities: printCapabilities, // from the info.json<br>
script in the html<br>
listeners:{<br>
beforeprint: function(){<br>
// test each layer<br>
// if the layer is vector, remove<br>
it<br>
from the printed legend<br>
}, // or use the "beforeencodelayer" function<br>
beforeencodelayer: function (printProvider, layer){<br>
// test each layer (easy with the layer<br>
parameter provided by this<br>
function!)<br>
// if the layer is vector, remove<br>
it<br>
from the printed legend<br>
}<br>
}<br>
});<br>
<br>
I hope it might help you!<br>
<br>
