Hey,
this is weird, I can see the Ajax loading during renderHead() processing
and then switch to my loading.
Maybe I could describe what I'm doing in more details (with
AjaxLazyLoadPanel being used):
Loader from AjaxLazyLoadPanel is displayed.
Remote REST is being called, response from REST is passed to JS function -
at this moment my panel is rendered.
JS then calls remote service via websocket, receives response, passed that
response to Wicket JS callback function.
This calls yet another REST endpoint and saves result into DB.
After that I replace my loading with success message.
I would like to "ideally" have all this covered by single loading panel.
