It looks like you can delay tasks via API : TaskOptionscountdownMillis(long countdownMillis) Set the number of milliseconds delay before execution of the task. TaskOptionsetaMillis(long etaMillis) Sets the approximate absolute time to execute. I also found a link :

I experienced this with lists of complex objects in owned relationships, not with lists of strings, see http://code.google.com/p/datanucleus-appengine/issues/detail?id=218 .

With the low-level API, you would just set the Key of the old object to the one one and persist it. With managed persistence via PersistenceManager or EntityManager, I believe you can set a key and merge (but I'm not sure off the top of my head). On Wed, Sep 8, 2010 at 12:43 PM, Shaun wrote: > T

BTW, you can use GWT in a manor very similar to JQuery. Take a look a GQuery by Ray Cromwell. He has an incredible benchmark page which dynamically shows how GQuery out performs JQuery in almost every measure. On 10 September 2010 05:53, John Patterson wrote: > You might want to look into Site
