What do you mean by becomes unbound to its source? I'd tend to think
that cloning feature+fid is a good solution...
Yeah, it's not very clear. What I meant is if I clone the feature,
modify the original then cancel -- if I destroy the original and
addFeature(clone), the clone becomes independent of the other features,
i.e. it was not added from a getFeature request, but manually.
Even when explaining it, it doesn't make much sense. It shouldn't
matter how a feature is added to a layer IMO. Maybe I did something
wrong again. I should make a sample and share it.
I'll let you know when I'm done.
Thanks
Alexandre
You were right. I don't remember what I did first but obviously I made
some mistake because feature.clone() + fid is working just fine.
Sorry for the noise.

== working cloning ==
olWFSRoads.events.register(beforefeaturemodified,
'', onRoadModificationStart);
olWFSRoads.events.register(afterfeaturemodified,
'', onRoadModificationEnd);
function onRoadModificationStart(evt) {
var oFeature = evt.feature;
// ### HERE ###
if(oFeature.state != OpenLayers.State.INSERT){
oFeature.myClone = oFeature.clone();
oFeature.myClone.fid = oFeature.fid;
}
};
function onRoadModificationEnd(evt) {
var oFeature = evt.feature;
// ### AND HERE ###
switch (oFeature.state)
{
case OpenLayers.State.INSERT:
olWFSRoads.destroyFeatures([oFeature]);
break;
case OpenLayers.State.UPDATE:
//olWFSRoads.refresh({'force':true});
olWFSRoads.addFeatures([oFeature.myClone]);
olWFSRoads.destroyFeatures([oFeature]);
break;
}
};

[OpenLayers-Users] Restore feature's geometry
Hi,
I'd like to know if there's a better (faster) way to restore a
modified feature's geometry other than using layer.refresh({'force':true});
I use a ModifyFeature control with a popup that as save and cancel
buttons. On save, it commits the changes (fine). On cancel, it should
'restore' the feature to its original state (at least the geometry).
I tried to clone the feature + fid before modifications, then on
cancel destroy the original feature and add the clone but it's obviously
wrong to do so since it becomes unbound to its source.
I also tried to clone the geometry only but I had weird behaviors
(duplicated features).
Any hint ?

Re: [OpenLayers-Users] Restore feature's geometry
Well, in the end I would really like to avoid the use of
layer.refresh({'force':true}) if possible.
If you activate the DrawFeature control while modifying a feature
(instead of hitting cancel), the geometry of the current modified
feature still needs to be restored (didn't hit the save button). So
the following happens :
1. layer.refresh is called
2. DrawFeature control activates (at the same time, featureadded
events are registered)
3. response from the layer.refresh draws new features, but they get
all engulfed in the DrawFeature featureadded events (resulting in
selecting them all in my case)
So, I would really need an other option... Any clue ?
I'll show the weird behavior of cloning the geometry in a live
example. Maybe I'm doing something wrong.

I registered the event on the Layer instead of the DrawFeature control.
That's why I had this behavior. Registering it to the control instead
solved that problem.
Still interested to hear more about other (and faster) options though.
