Juan Pablo Santos RodrÃguez commented on JSPWIKI-659:
-----------------------------------------------------
Hi,
JSONRPCBridge needs to be in session to enable javascript access to all classes
implementing org.apache.wiki.rpc.RPCCallable (cfr. [related link to
jsonrpc|http://viralpatel.net/blogs/calling-rpc-in-javascript-using-json-rpc-java/]).
In this case, seems to me that JSONUserModule#getUserInfo() gets called at
./src/webdocs/templates/default/admin/UserManagement.jsp, line 44.
Aside from JSONUserModule there are 3 more classes implementing RPCCallable,
with functionalities related to search, file upload and a sample plugin with
AJAX support.
Declaring UserManager transient inside JSONUserModule seems to be insufficient
to make it Serializable (cfr. http://stackoverflow.com/q/7144912). Haven't
tested yet, but promoting JSONUserModule to a first level class instead of
being an inner class would take away the exception. If that's the case, I think
we could do this in 2.9.1, doesn't seem to me like a class used for extending
JSPWiki...
br,
juan pablo
