Lukas, nice to see someone figured out my cryptic UI :).

No, it's not.  The current behavior is to request from the server that
they be sorted by date, although I think this only works for some versions
of apache.  Sorting by version number would be fine.  But what do you do
with versions that are named, or don't use the default sequential
versions?  For example, you might have a list like this:

Strictly speaking, you can't filter by package just from the filenames,
since the naming conventions aren't enforced.  Realistically, though, yes,
you could do this, as a stopgap until we have the "VersionInfo feed" we
were talking about earlier.

Why are we sticking to menus?  With a list that long, wouldn't it maybe be
better to bring up a dialog with a scrollbar?
Then you could also have Load, Merge buttons as well as Open, in case you
already know the exact version you want.

Go for it.

Well, the difference here is that it is always the UI itself that is
calling #open - so there is no need for the indirection of an exception,
the UI can easily know whether to call #morphicOpen or #seasideOpen:.

You could do something like this:

pickVersion: aBlock
  picked := aBlock value: self allVersions.

  self pickVersion: [:list | ....]

  self pickVersion: [:list | ...]

Or maybe some OpenVersionDialog model that you could build both Seaside
and Morphic views from (hey, just a random thought - have you looked at
MCTool?  Could one build a Seaside renderer for the #widgetSpecs?)
