[OpenLayers-Users] Bug in LoadingPanel + testcase

[manel.clos at ajgirona.cat]

Hi,

there is a bug in LoadingPanel that prevents wheel events from being processed. This happens only when used with OpenLayers.Control.Navigation.

It works with the default usage:
http://dev.openlayers.org/addins/loadingPanel/trunk/examples/loadingpanel.html

but making these changes to the same example will allow anyone to reproduce the bug (tested in FF3 and IE7):

in the init function:
...
//   map.addControl(new OpenLayers.Control.PanZoomBar());
//   map.addControl(new OpenLayers.Control.MouseToolbar());
   map.addControl(new OpenLayers.Control.Navigation());
...

this is, comment out PanZoom and MouseToolbar and add Navigation.

If loading panel is showing because tiles are loading, you *can not* use the mouse wheel to zoom in/out. After loading or deactivating the loading panel mouse wheel works as usual.

Here are some previous reports that may offer some more details on the problem:
