Hi, Can't you just pass the additional parameters also along in JSON format? If you are using the paging by key the bookmark can be pickled and converted to JSON format.
I have not tested or used it with any of the below suggestions, 1. try the normal picked object. if that does not work 2. http://ajaxian.com/archives/json-pickle-serialize-your-complex-python-objects-to-json If your question was how to parse JSON in python, Django framework comes bundled with simplejson and its included in the GAE SDK. Thanks, Arun Shanker Prasad.
