Hi Adam,<br>thanks a lot for the quick reply.<br>I now activated the 'extent'-option, but the result is still the same, no feature-rendering. I don't think it's related to the missing "zoom/center"-options, but as I'm quite new to GeoExt/OL so I can't rule it out for sure.<br>
Cheers<br>Andreia<br><br><br><br><div class="gmail_quote">2010/8/16 Adam Ratcliffe <span dir="ltr"><<a href="mailto:adam@prema.co.nz">adam@prema.co.nz</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
HI Andreia,<br>
<br>
I note that you've commented out the 'extent' option in the MapPanel<br>
configuration and you have no 'zoom' and 'center' options specified -<br>
could that be the problem?<br>
<br>
You could try adding the vector layer to the map and letting the<br>
MapPanel create a LayerStore for you from the map's 'layers' array,<br>
though looking at the docs the 2 approaches look like they should be<br>
equivalent.<br>
<br>
Cheers<br>
Adam<br>
