Hi,
Exists any way to check if an App Data was Stored?
In example below, I never stored an Orption with "hasUserAnunc".
Like this:
function IsAnunc(){
var req = opensocial.newDataRequest();
req.add(req.newFetchPersonAppDataRequest(idspec,
"hasUserAnunc"),"userAnuncData");
req.send(processIsAnunc);
};
function processIsAnunc(response) {
var data = response.get("userAnuncData");
if (data == null){
}
};
I need this, because I wanna record a option only in the first time
that the Owners App acess.
Sorry about english, I'm Brazilian...
Tks
