Hi Johan,
It looks like you did not export properly the ports from the inner browser
(propertiesSelector2). Could you paste that here?
Cheers,
Doru

shows the text nilnilnilnilnilnil . How do I fix this? Thanks in advance!

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 ].
Thanks for helping out, but the problem remains the same: the parameters passed to the
block are *always* nil when I allowNil, and when I dont allowNil the browser only displays
the parameters when all 6 lists have a selection. a when: does not help here (in either of
both cases).
Anybody got any other ideas?
