Thank you Mark, that was very helpful!
My main mistake was that I was trying to obtain the result of the list
widget before using it, instead of using the variable inside the list
loop. Indeed it makes sense that the emptyMessage parameter doesn't
work, since it is not assigned to the list variable.
I was able to simplify your version a little: no need for the original
macro as you mentioned, emptyMessage is not needed anymore, and I use
the default list variable currentTiddler; I'm copying it below in case
anyone else is interested.
Thanks again!

I think anything evaluated within List needs to be "real" That is, the
emptyMessage doesn't work the same as if you got real results. I'm
sure someone will correct me on this if I'm wrong.
What I did was to
*(1) Change the filter so that something always gets iterated, *
*(2) enclose the button invocation inside list instead of set and use
the variable feature to specify a "mytag" as the output, *
*(3) Create a macro to wrap mytag in brackets*
*(4) Use the wrapper with the tags attribute*
Maybe other stuff. It seems to work, assuming that your use case was
that you wanted to invoke the button from preview mode and/or from the
closed tiddler. I'm not sure if you even need the macros at this point
other than the new wrapper macro. You can check that out if you want.

Hi everyone,
I'm trying to create a button based on the "new journal here" which
would work even if the current tiddler is in edit mode. I can
obtain the
real title of the tiddler with:
<$list filter="[all[current]get[draft.of]]"
emptyMessage={{!!title}} />
but I didn't find how to pass the result to the "tags" parameter
in the
action-sendmessage widget. I assume that I need to obtain the
result as
a string before transmitting it as a parameter, but I'm confused
about
when a macro or widget is actually evaluated. (I also tried using
"macrocall" but probably not the right way)
This is what I have currently:
\define nonDraftTitle()
<$list filter="[all[current]get[draft.of]]"
emptyMessage={{!!title}} />
\end
\define evalNonDraftTitle()
<$macrocall $name=nonDraftTitle/>
\end
\define journalButton()
<$button
tooltip={{$:/language/Buttons/NewJournalHere/Hint}}
aria-label={{$:/language/Buttons/NewJournalHere/Caption}}
class=<<tv-config-toolbar-class>>

{{$:/core/images/new-journal-button}}
</$list>
<$list filter="[<tv-config-toolbar-text>prefix[yes]]">
<span class="tc-btn-text">
<$text text={{$:/language/Buttons/NewJournalHere/Caption}}/>
</span>
</$list>
