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>
