this renderer, etc." message ?
Again, even if we make the macro use only wiki syntax, it will be an
empty table, which is IMHO worse than an empty space (users will be
wondering that is supposed to be).
Of course we can think of an alternative to be displayed (which I
believe is not an easy task for a live table, since you'll never want to
display a table with 30.000 entries, so displaying the whole table is...
out of the table), but we'll have the case anyway with potentially lot
of other things. (How do you render a canvas element ? a flash object ?
an applet ? etc.) I really think we'll need a way to display an "excuse
message".

Hi Vincent,
Note the livetable is an empty table everywhere you don't have
JavaScript.
Inserting the select in JavaScript sounds a bad idea to me. It would
be
a hack to hide form controls (button, select, etc) to renderers for
which they do not have sense. But those form controls are meaningful
in
the macro, to me a form is something that by itself justify the use of
the HTML macro. (and actually I'm not sure you can do that trick that
easily, since the select values are generated server side from
velocity).
I'm completely convinced we have to use standard wiki syntax as much
as
possible, but we should also keep in mind that some macros will not
make
any kind of sense anywhere but in a browser. Can renderers that do not
support HTML fragments just drop them (eventually outputting a message
to say a part of the original document is missing) ?
Yes that's the problem: they'll be dropped. So instead of a table with
data it'll be an empty space.
That said we need to think how we'd want a livetable to be displayed
in other renderers.
As I said that's not a problem we have now but we need to be aware of
it since it'll crop up again one day.

Thanks,
Jerome.
