This basically works. Thanks a lot!
But there seems to be a display error.
The example code here should clarify the problem:

require(rkwarddev)
local({
  foo.input <- rk.XML.radio("Foo input",
    id.name="foo_input",
    options=list(
      "Show me foo"=c(val="show"),
      "Skip foo"=c(val="skip")
    )
  )

  foo.input.page <- rk.XML.page(foo.input)
  foo.page <- rk.XML.page(rk.XML.text("foo"))
  bar.page <- rk.XML.page(rk.XML.text("bar"))

  full.wizard <- rk.XML.wizard(label="test", foo.input.page, foo.page, bar.page)

  foo.input.convert <- rk.XML.convert(sources=list(string=foo.input),
mode=c(equals="show"), id.name="foo_input_convert")
  foo.page.connect <- rk.XML.connect(governor=foo.input.convert,
client=foo.page, set="visible")

  logic <- rk.XML.logic(foo.input.convert, foo.page.connect)

  plugin.dir <<- rk.plugin.skeleton("test",
    xml=list(wizard=full.wizard, logic=logic),
    pluginmap=list(name="test", hierarchy=list("test", "test")),
    load=TRUE,
    edit=TRUE,
    show=TRUE,
    overwrite=TRUE
  )
})

When you run the wizard, the foo.page is already shown on top of the
foo.input.page and its visibility can be toggled using the radio input.
The same effect occurs if you do the following:
  1. Select "Show me foo"
  2. Click "Next"
  3. Click "Previous"
  4. Select "Skip foo
  5. Select "Show me foo"
