Hi,<div><br></div><div>Well i tried it on a window and still the same error occurs. So it is definitely a LegendPanel bug. If i don't use a LegendPanel at all, there are no problems.</div><div><br></div><div>You are right when saying that it doesn't affect map navigation. However, because i'm using 2 different projections in the app (spherical mercator and etrs) when reprojection happens, and only after removing a vector layer, the map gets confused and gets out there in the world but not where it should be. If i don't remove any vector layer reprojection works just fine.</div>
<div><br></div><div>So, in my case, this bug is crashing some fucntionalities.</div><div><br></div><div>I'm thinking in a workaround by just defining a specific url for the legend of vector layers and have an image on the server. Maybe that works but is not a pretty solution specially if you want to give the users the possibility to change the style of such layers.</div>
<div><br></div><div>Does someone have more thoughts on this?</div><div><br></div><div>Regards,</div><div>Hugo <br><br><div class="gmail_quote">On Thu, Oct 13, 2011 at 2:52 PM, gbrun <span dir="ltr"><<a href="mailto:gbrun@myopera.com">gbrun@myopera.com</a>></span> wrote:<br>

But in my memories, this problem didn't affect the navigation in the map, did it? I only received error messages in firebug.<br>
<br>
I didn't find a solution to fix this bug: so I isolated the LegendPanel component from the others panels by giving it its own window. Maybe you can try this clue: it could help you to define if it's a LegendPanel bug.<br>

Hi Geoffrey,<br>
<br>
Indeed i have a viewport with a left panel and a map panel (in center<br>
region). My left panel is a tabpanel which has a treepanel and legend panel.<br>
The thing is even if i don't collapse the left panel i get this error just<br>
by doing a zoom in the map. Even when changing the layout i get the same<br>
error. At the moment i have no idea where to start to debug this...<br>
How did you solved it? Any more suggestions?<br>
<br>
Thanks in advance,<br>
Hugo<br>

Hi Hugo,<br>
<br>
My question would probably be surprising for you! Do your LegendPanel use a<br>
"border" layout shared with an other panel (a MapPanel precisely? I got a<br>
similar bug: this one appeared when I collapsed/expanded the LegendPanel<br>
after removing a layer.<br>
<br>
I'm not sure your problem is related to this one, but perhaps?<br>

Hello all,<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
I'm facing a small but annoying problem with vector legends. I'm using<br>
JSTS<br>
(which i think it is an awesome contribution for geoprocessing operations<br>
on<br>
the client side) to compute buffers. So the user defines the parameters to<br>
compute a buffer and a new vector layer is added with the result. Untill<br>
now<br>
everything is fine, and GeoExt.LegendPanel shows the legend for this<br>
layer.<br>
In the app, the user has also the possibility to select several layers and<br>
completely remove them from the map. It is exactly here that the problem<br>
arises. After removing a vector layer from the map i start to get an error<br>
related with vectorlegend.js. From that point onwards, everytime i make a<br>
zoom in the map i get the following error:<br>
<br>
this.layer is null (on line 256 of vectorlegend.js:<br>
this.layer.map.getScale())<br>
<br>
This only happens after removing vector layers from the map. So i thought<br>
i<br>
had to manually remove the layer from the legendpanel but, as expected,<br>
the<br>
layerstore of the legendpanel is synchronized with the mapPanel<br>
layerstore<br>
and, therefore, the layer is no longer present at both stores.<br>
<br>
So, what might be the issue happening here?<br>
<br>
Regards,<br>
Hugo<br>
