my problem is that I need 1 event before the WFS request is sent, so that I can clear my store for a grid. I also need one after all the featureselected events have finished for the box query, so that I know I am done and that I can reconfigure my grid with the new store.
The beforefeatureselected events are fired as many times as the featureselected, so that does not work for me.
Also, is there a good way to have both hover and box? When drawing a box, also the hover goes off, which is a bit unwanted IMHO.
