Hi list,<div><br></div><div>I have a vector layer with some points, and when I create a new point, it is added to the vector layer and saved correctly in the datasource.</div><div>But, if I do a zoom in, the only feature I can see is the last new one, the other aren't displayed anymore. </div>
<div>After debuging the code, I've seen that when the success event of the save strategy is raised, there is only the last feature in the layer.. And of course, only that one is drawn.</div><div>When I reload the page, all the new faeatures are loaded and displayed ok in the map.</div>
<div><br></div><div>I do the following to load and create points: </div><div><br></div><div><div>function init(){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>oSaveStrategyPoint = new OpenLayers.Strategy.Save();</div>
