Sample

<div id="msg" style="visibility: hidden"></div>

Ext.get('okButton').on('click', function(){
  var msg = Ext.get('msg');

    text: 'Updating...'

Errors

When you try to load a page with UpdateManager that doesn’t exist or returns an error, the loading indicator will show forever.

The original sample includes parameters in the call to msg.load()

msg.load({
  url: [server url], // <-- replace with your url
  params: 'name=' + Ext.get('name').dom.value,
  text: 'Updating...'
});

As we can see from this forum post if you pass params to load it does an HTTP POST; otherwise it does a GET.

I used curl to do a POST on this URL and it returned an HTTP Status 405 error…

Here are a couple of forum discussions:
