Problem with WFS/Popups in Firefox<br>
</span></font><font size=2 face=Arial><span style='font-size:10.0pt;font-family:

Hi List,<br>
<br>
I now solved the database-problem that caused some popups not to be filled with
information when you click on a symbol. I also checked the projection as Marc
proposed, but that didn't help. I still have the problem in Firefox (and only
in Firefox, it until now did never occur in IE!) that after zooming twice AND
panning the map, some popups (not always the same!) have an offset and don't
open directly at the symbol but somewhere else in the map.<br>
<br>
You can see here: <a
href="http://217.78.131.132/dev_ol/ol_print/ol_viewer_neu_layout_suche.html"
target="_blank">http://217.78.131.132/dev_ol/ol_print/ol_viewer_neu_layout_suche.html</a><br>
<br>
Second problem, this time only in the Internet Explorer: Sometimes, not always,
there occurs no map, the part of the map is white and empty after having
startet. When you then refresh IE it works fine... It would be great, when you
could test the page and give me feedback whether it occurs or not and which
IE-Version you are using.<br>
<br>
Has anybody an idea???<br>
Thanks a lot and greetings<br>
Barbara<br>

Hi Barbara,<br>
<br>
If I click on a feature located at POINT(2552356 5693550) (near <br>
Angerhausen, South of Duisburg) I get a GetFeatureInfo-Request with the <br>
BBOX 2546405, 5692856, 2547405, 5693856. And of course the popup is <br>
placed at the wrong coordinates and the GFI-Request is empty.<br>
<br>
IMO you should try to search the error in the BBOX creation-function.<br>
<br>
Regards,<br>
Marc<br>
<br>
PS: I'd guess that this problem should arise in IE as well... haven't <br>
tested though.<br>
<br>
