TYPO 3 6.1: Change the rendering of a custom content element depending on the backend layout

I try to write a custom content element which should be rendered depending on the backend_layout or the inherited backend_layout of the page the content element is contained in.

My first attempt

I've got theTypoScript snippet in my template:

lib.layout = CASE
lib.layout {
    key.field = backend_layout
    key.ifEmpty.data = levelfield:-1,backend_layout_next_level,slide

    1 = TEXT
    1.value = START-PAGE-LAYOUT

    2 = TEXT
    2.value = SINGLE-COLUMN-PAGE-LAYOUT

    3 = TEXT
    3.value = TWO-COLUMN-PAGE-LAYOUT

    default = TEXT
    default.value = DEFAULT-OUTPUT
}

If I try to render this in my plugin view like this

<f:cObject typoscriptObjectPath="lib.layout" />

I get

DEFAULT-OUTPUT

I would expect one of the other three as output.

My second attempt

I also tried 

plugin.my_contentelement.settings.layout < lib.layout

and then to use the ContentObjectRenderer but got only the default output.

My question

Does anybody has a nice solution for my problem?

PS: I use TYPO3 6.1.5

key.field should work as by default the current data array is populated by the page data. I don't know why it doesn't work in your case so try this code instead:

lib.layout = CASE
lib.layout {
  key.data = page:backend_layout
  key.ifEmpty.data = levelfield:-2,backend_layout_next_level,slide

  1 = TEXT
  1.value = START-PAGE-LAYOUT

  2 = TEXT
  2.value = SINGLE-COLUMN-PAGE-LAYOUT

  3 = TEXT
  3.value = TWO-COLUMN-PAGE-LAYOUT

  default = TEXT
  default.value = DEFAULT-OUTPUT
}

For levelfield:-1,backend_layout_next_level,slide to work, you probably need to add backend_layout_next_level (and better also backend_layout) to $TYPO3_CONF_VARS['FE']['addRootLineFields'] in the installation config file.

Shouldn't it be: 

lib.layout = CASE
lib.layout {

Additionally you should replace ifEmpty with override and do it the other way around, since TSref says: If the content is empty (trimmed) at this point, the content is loaded with "ifEmpty". Zeros are treated as empty values!

lib.layout {
    key.data = levelfield:-2,backend_layout_next_level,slide
    key.override.field = backend_layout

    1 = TEXT
    1.value = START-PAGE-LAYOUT

    2 = TEXT
    2.value = SINGLE-COLUMN-PAGE-LAYOUT

    3 = TEXT
    3.value = TWO-COLUMN-PAGE-LAYOUT

    default = TEXT
    default.value = DEFAULT-OUTPUT
}

Setting it explicitely to "None" has a value other than zero, so this should be working.
