[orkut-developer] Re: IMPORTANT: Name Collision Protection launching! Don't change the title of your app!

[Bruno Oliveira (btco)]

Hi,

We've tested it a lot in our labs and we're pretty sure it will work well. 
The signal that triggers the check is changing the app's title (in any 
language). So if you don't change your title, there is no way your app will 
be taken down.

Question: what about existing applications that have name conflicts?

They will not be checked unless they change their names. If there are 
existing applications with conflicting names, we have no way to decide which 
one is the right one, so we won't take down any of them. The only way to 
take down an existing app that has a name that belongs to you is to file a 
DMCA complaint.

Thanks for this great post! :-)

It's a good thing you brought up point #1, it can be frustrating to many 
developers. It's always a good idea to include a version number in your XML 
to make sure you are debugging the right thing. We also cache other 
application assets, so if you just updated a graphics file that you are 
using, you may not see changes immediately.

Another relevant point is that you should always do error handling on the 
callbacks:

function callback(data) {
   if (data.hadError()) {
  // handle error
   }
   ...
}

Why? Because if you don't check and try to operate on the data anyway, you 
may get strange 'null' and 'undefined' values. I remember spending a few 
hours scratching my head at this when I had just started learning 
OpenSocial. So the bottom line is: always check for errors!

By the way, you can get the error message like this:

data.getErrorMessage()

And the individual error messages for each of your requests like this:

data.get('your_id').getErrorMessage()

Another very important point I'd like to emphasize is #2: use a Javascript 
console or debugger so you can see if you have any syntax errors or runtime 
errors!

Again, congrats on the great post and keep up the good work! :)
