yeah I've go that, the dependent code is in _handleData()
The problem is more than that. consider the following:
var Spiral = Class.create({
data:null,
initialize: function()
{
var req = opensocial.newDataRequest();
req.add(req.newFetchPersonRequest("VIEWER"),
'viewer');
req.send(this._handleData.bindAsEventListener(this));
alert('send is done');
},
_handleData: function(data)
{
this.data = data;
alert('data received');
},
})
this will alert in the following order:
'send is done'
'data received'
and an even bigger problem, I don't know how to tell when the send is
finished so that I can alert the rest of my code. Also, if the
callback function is an optional parameter, is there a different way
to get the data? Will send return the data so that I can make it run
line by line?
