Re: Few problems with creating/ updating entities with requestfactory and appengine

Hi Juan

1. I added @Basic annotation with fetch type eager and it works. Till now I was pretty sure that embedded object are always fetched and I thought that this problem is related to the appengine.  

2. Here is my persistence.xml file. Do you suggest that I should use transactions to get it working ? I'm using appengine for the first time and this app is actually testing app, I'm testing the  new api Editors, RF. That's why i don't know much about appengine and its datastore.
