[OpenLayers-Users] Unable to Rollback changes on WFS update failure

[Adrian Popa]

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
