I don't know anything about tgext.menu, but two remarks:
- the above obviously can't work, as it's run only once per controller
instance. *If* tgext.menu is dynamic enough by itself, you need to stuff this
code into a place that's run every time in a request - e.g. the variable
providers.
- I would use a widget for this. Probably also stuffed into the variable
providers, and rendered by the master.html.
