RequestFactory Refractory Long Id into String Id, so I can use App Engine Keys??

[Brandon Donnelson]

I think the RequestFactory ID system should be a String and not a Long so we can use child collections on App Engine easily. App Engine keys can be reflected as Entity(1)/Entity(2)/Entity(3)... . I would think this wouldn't require a Key serialization routine. 

Any Thoughts?

I dont know App Engine but if you implement a Locator for your entities you can use any type as Id. Works pretty well (I have a sample project that uses String UUIDs as Id for entities).

I just figured I ship the Ids as string, and its working fine. I noticed the source was not particular to what type of ID it is. So I'll serialize the App Engine key. I suppose Long has more type safety. 

Thanks for commenting to that helps Jens.

RequestFactory now works good with AppEngine if your Id's are Keys in Strings.

This is what I end up doing:

 public void setId(String id) {
    if (id == null) {
      return;
    }
    key = KeyFactory.stringToKey(id);
  }
  public String getId() {
    String id = null;
    if (key != null) {
      id = KeyFactory.keyToString(key);
    }
    return id;
  }
