Dear list,
I have the following sample:
\setupexternalfigures[location=default]
\starttext
\startxtable[option={stretch, width}]
\startxrow
\startxcell
\dontleavehmode\dorecurse{100}{
\externalfigure[cow.pdf][scale=50] }
\stopxcell
\startxcell
\input zapf
\stopxcell
\stopxrow
\stopxtable
\stoptext
Some time ago, there were no difference between images and text
remaining inside the frame.
Have I hit a bug or what am I missing there?
Many thanks for your help,
Pablo

Not a solution but closer to the problem.
Commenting the \local(left|right)box settings brings the line breaks back.
\everyforgetall\emptytoks
\appendtoks
\localleftbox {}%
\localrightbox{}%
\to \everyforgetall
\setupexternalfigures[location=default]
\starttext
\vbox
{\dontleavehmode
\dorecurse{100}
{\externalfigure[cow.pdf][scale=50] }}
\stoptext
Wolfgang

Ah, a pretty clever analysis!
This side effect has puzzled me for a while (adding an \allowbreak also
works). The solution is simple:
- i don't reset when not set (only happens in some special delimiters case)
- i added a safeguard to luametatex (we can't change luatex behaviour)
not to inject an unneeded local par node (which is the cause of the
problem) when there is no local box in use
(As setting these boxes can be changed mid par their state is registered
in the node list in order to be taken into account when a paragraph is
made. It's a bit pain-in-the-butt mechanism with potential side effects,
also in terms of memory management. When it was incorporated (irr it
comes from aleph) it was basically broken but stepwise it got fixed. So,
it seems another corner case had to be catched. Thanks for noticing.)
