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!

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 | ... ]
