Updated The EIDReader applet documentation after a nightly session with Dirk.

Fixed a NameError found by the welfare online demo: “global name ‘exceptions’ is not defined” at /restful/extensible/PanelEvents

Continued to research on The EIDReader applet with Manuel who taught me some important tricks: in the Oracle Java console I must use

  • x to clear the classloader cache
  • 5 to set trace level to maximum

As a souvenir, here is one of our traceback:
