It's hard without seeing any code snippets to know exactly what you're
getting at.  What is the block that you're passing in to
#anchorWithAction:text:?

The general pattern I use with navigation components like that is to pass
them in a 'target'.  So, if the actions of the menu items are affecting
the MainPage, when you create your MenuBar you would pass in that
component:

bar := MenuBar new target: mainPage.

The MenuBar might in turn pass this on to its items:

items add:
  (MenuItem
     target: target
     selector: #doStuff
     description: 'Do Some Stuff')

Rendering the menu item might then look like this:

MenuItem>>renderContentOn: html
  ...
  html anchorWithAction: [target perform: selector] text: description.
  ...

How closely does that match what you're doing?
