Hi,<div><br></div><div>After testing a little bit more, i found that if i use this code in the beforeprint listener it still complains about the encoding itself. So, i moved this code to the handler of a print button before calling the print method. Using this approach it works somehow but it removes all my vector layers from the map. As you told, i have cloned the legendPanel (using Ext.apply) and still get the same issue, all my vector layers are gone.</div>
<div><br></div><div>Here is the current code:</div><div><br></div><div><div>var cloneLegPanel = {};</div><div>Ext.apply(cloneLegPanel, legendPanel);</div><div>var legLayerStore = cloneLegPanel.layerStore;</div><div>legLayerStore.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.Vector'){</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>legLayerStore.remove(record);</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>}</div><div>});</div><div>printProvider.print(mapPanel, printPage, {legend: cloneLegPanel});</div>
<div><br></div><div>With this code i get the legends in the mapfish print pdf but i cannot print vector layers and they are removed from the map.</div><div>What would you suggest? The thing i don't understand is why my vectors layers are being removed when i'm using a cloned object of the GeoExt Legend Panel. Any ideas?</div>
<div><br></div><div>Thanks once again,</div><div>Hugo</div><br><div class="gmail_quote">On Fri, Oct 7, 2011 at 2:09 PM, gbrun <span dir="ltr"><<a href="mailto:gbrun@myopera.com">gbrun@myopera.com</a>></span> wrote:<br>

Vector layers are completely removed from the map, not only from the legend panel? In this case, you should indeed clone your legend. Then, you could remove vector layers from this cloned legend. A the end, you can 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 my app, I have deactivated the "print legend" capabilities when a vector layer is contained in a map.<br>

Hello Geoffrey,<br>
<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>
var includeLegend = Ext.getCmp('includeleg').<u></u>getValue();<br>
if (includeLegend == true){<br>
var legOpt = printOpt.legend;<br>
var legLayerStore = legOpt.layerStore;<br>
legLayerStore.each(function(<u></u>layerRec){<br>
var layerDef = layerRec.get('layer');<br>
if (layerDef.ClASS_NAME == 'OpenLayers.Layer.Vector'){<br>
legLayerStore.remove(layerRec)<u></u>;<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>
Hugo<br>

Hi!<br>
<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 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 it<br>
from the printed legend<br>
}<br>
}<br>
});<br>
<br>
I hope it might help you!<br>
<br>
