I found a workaround for anyone interested:


\setupinteraction[state=start,focus=standard]

\starttext

\startplaceformula[title=$\alpha$,reference=alpha]

\startformula

1 + 1 = 2

\stopformula

\stopplaceformula

\dorecurse{20}{\samplefile{knuth}}

I'm in \in{$\alpha$}[alpha] %so the reference is now visible

\stoptext

However, one has to manually write a label and a title independently, so I'm not sure that's a clean solution...

Best regards,

Jairo

Hi again. The following doesn't work (the tag is missing):

\startTEXpage[offset=2bp]
\startplaceformula[title=A,reference=alpha]
     \startformula
         1 + 1 = 2
     \stopformula
\stopplaceformula
I'm in \in[alpha]
\stopTEXpage

Oh, dumb me, sorry for the noise and thank you very much. Not every day is a good one, sorry again.

Define 'expected' ... \eqno is something low level (a primitive) and we
have that nilled at the user level and only use it deep down. It was
never meant as user command.

\startTEXpage[offset=2bp]
\startplaceformula[title=A]
     \startformula
         1 + 1 = 2
     \stopformula
\stopplaceformula
\stopTEXpage
