[OpenLayers-Users] Getting server output when using save

[Gabriel Nolasco]

Adrian,

Try something like this:

var saveStrategy = new OpenLayers.Strategy.Save({
  onCommit: function(response){
    if(response.success()) {
      alert(response.priv.responseText);
    }
  }
});

Best regards,
Gabriel Nolasco

Hello everyone,

I'm trying to create a callback function for the save strategy so that I 
can display a status message for the user in case there are problems 
with saving their changes (e.g. - session expired, etc).
I want the serverside script to send back a JSON formatted string that 
would describe what the problem was - for instance: 
({'failure':true,'error':'You do not have rights to make changes'}). I 
indend to eval this message and extract the error and show it to the user.

I have created a trigger that fires on "success", but I can't find 
anywhere the response from the server (so that I can parse it):

var saveStrategy = new OpenLayers.Strategy.Save();
saveStrategy.events.on({'success': function(event){
        alert("On save success");
}});

The event parameter that gets passed to the function has a 
"Strategy.Save" object and a "Protocol.Response" object. By browsing 
both of them I still couldn't find the original message returned by the 
server.

By the way, the server returns content-type text/html.

I noticed that the failure event is triggered when the server returns a 
500 error, but I wouldn't want to have to crash my server-side script on 
purpose in order to catch a problem on the client-side.

Am I missing something or doing something wrong?

Thanks,
Adrian
