Hi Dirk, Yes, you're understanding what I'm trying to do. In addition to the plugin I've also been using a bespoke JSP page with scriptlets to prototype ideas quickly, as well as a JavaScriptPlugin we wrote years ago as a test bed. (That could be submitted as a replacement for the JSPWiki plugin of the same name if people are interested.)
I have tried the 'domready' wrapper you suggested but that didn't seem to make any difference, and given the amount of time I've now spent on this I have to say that I'm likely going to abandon any AJAX-related work in the JSPWiki space until it at some point as moved over to jQuery, and there's a working RPCSamplePlugin. I've just run out of both steam and time. For now I'll probably try using some other approach than the JSONRPCManager since I just can't get that to work. Perhaps Apache Wink or some kind of lightweight RESTful client-server thing, dunno. Thanks very much for all your help, Ichiro
