Hello Hugo, hello Geoffrey, hello all,<br>
<br>
Thanks for reporting this issue.<br>
I could reproduce the error and therefore I opened up a ticket [1].<br>
Further discussion should be done there.<br>

Best rergards,<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>
<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>Does someone have more thoughts on this?</div>

zooming into the map, beside the collapse/expand issue. 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>
<br>

<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>
