Hi Yong With respect to your second question. I have the same question. So far: I have found in the GadgetFactory class two methods addSubstitutions and applySubstitutions. This class is used by MetadataHandler which handles the metadata request. It looks to me like this is the point where one should apply the substitutions to restore the user's preferences. The GadgetFactory class has the gadget url available as $this->context->getUrl(); and the token as $this->token assuming the service was called with a token, so one could use these to access the stored values I guess. This is what I'm planning to do but to be honest I'm not 100% sure. I'm fumbling around in the dark a little. Hope that helps even a little bit. Justin
