Hello,
It seems to me that you're not checking the problem where you're
supposed to.
onCommit returns the reply from the server, so it's the server's job to
accept or reject the changes. If the server rejects the changes, you can
do just this.layer.refresh({force: true}); and you will get the old data
(and the new data will be discarded).
Good luck

Hi,
I'm trying to create an editable map based upon the OpenLayers
wfs-protocol-transactions example. On some occasions (for example when
other users have updated features) I want to abandon the outstanding
edit on a feature and redraw it as it was originally obtained from the
base WFS service. I couldn’t work out how to do that and have reverted
to trying to redraw the entire layer using the layer.redraw and
layer.refresh functions. Unfortunately nothing seems to work. The
features stay as drawn, which no longer matches what is in the
geoserver service. How do I do some equivalent of "undo this feature
and cancel any pending changes on it", or alternatively “refresh this
feater (or if necessary all features) from the WFS service. The code
fragment I have at this point is:
var saveStrategy = new OpenLayers.Strategy.Save
({
onCommit: function(response)
{
if (response.success())
{
alert("Good");
alert(response.priv.responseText);
} else {
alert("Bad");
alert(response.priv.responseText);
}
if (confirm("Do you want to abort this request ?"))
{
alert("Abort request here");
this.layer.refresh(true);
this.layer.redraw();
}
}
});
wfs = new OpenLayers.Layer.Vector("Editable Features", {
strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
AND SO ON...
Any Suggestions ?
