[OpenLayers-Users] How connect the editing toolbar to a layer on the fly

[Arnd Wippermann]

In parts I have managed in a easy way to swap the control from one layer to
another.

editControl.destroy();
var lyr = map.layers[AktLyr];
editControl = new OpenLayers.Control.EditingToolbar(lyr);
map.addControl(editControl);

But I have used the editingtoolbar.js, have it modified to insert a button
for selectFeature and modifyFeature.

When I first add the toolbar to the "Editable" layer, all buttons work. When
I swap to another layer, it works also. But when I swap a second time the
two added buttons works for the previous layer and not for the new one. This
means, I can draw features on one layer, but I'm not able to select this
features.

Mit freundlichen Grüssen

This should be made easier.

If you want to see how I've done it, take a look at the (not for production,
not to be considered stable, for demonstration purposes
only) FeatureEditor control with a change layer method:

http://trac.openlayers.org/browser/sandbox/tschaub/wfsv/lib/OpenLayers/Contr
ol/FeatureEditor.js#L162

All that should be cleaner.  Basically, you need a way to swap out the
handler that the draw/modify controls use.
