OK we are almost there ... one last hitch (see test code below). if I dont add allowNil
the text browser only shows text if all 6 lists have a selection. I want to be able to
have a list without selection (= no metric), so I added allowNil, but that always shows
the text nilnilnilnilnilnil . How do I fix this? Thanks in advance!

browser := GLMTabulator new.

Usually one inserts a when: clause to activate the pane when a specific parameter is not
nil (because at least one should be not nil to display something). But in your case it
seems different: the status is always active, but it should filter the nil in its display:
block
Something like (warning, not tested!)
using: [browser text display: [ :cw :ch :aw :ah :mw :mh | {cw. ch. aw. ah. mw. mh}
select: #notNil thenCollect: #asString ]; allowNil ].

I
understand the sendToOutside: part, but I dont see how the outside receives these
selection messages and can store the selections, e.g. in a local variable. Can you
enlighten me here?
When you have multiple #from: statements, you will get multiple variables in the
#display: block. Something like this:
outerBrowser showOn: #main; fromOutside: #entity; from: #properties->#selectedCHeight;
#properties->#selectedCWidth; using: [
browser mondrian
painting: [:view :cheight :cwidth | ... ]
]
