set the caching time to infinit (-1). That way the content should be cached after the first render until the portlet receives a render or action request that is directly targeted at the instance.... (in theory at least ;)
Thanks, I'll give it a try and report back.
I was just wondering if that worked for you.
I would like to put together a prototype and adding Google maps would be a nice enhancement.
What did you do to make it work? Was there anything unique about the code? I'd like to avoid simply putting it in an iframe portlet.
