And \startcombination\stopcombination fails when you use \placefigure instead of \externalfigure because you want the captions to be numbered and included in the list of figures. You get an error like this one 

      > tex error on line 7 in file virtual: . . .  ! You can't use `\prevdepth' in restricted horizontal mode

Using \startfloatcombinations\stopfloatcombination (which appears to be undocumented) avoids this error.

I thought that nesting combinations might enable this type of combination but it didn’t work. see
https://mailman.ntg.nl/pipermail/ntg-context/2016/084926.html <https://mailman.ntg.nl/pipermail/ntg-context/2016/084926.html>

Using tables is a better solution because it has the syntax to handle figures that span rows or columns

Lots of things seem to work well with external figures but as soon as you embed them in a \placefigure, which makes them a float, you make things more complex and run into the possibility of triggering the restricted horizontal mode  error.

It seems to me that once you place an object that is normally a float inside another float you want the inner one to lose it floating characteristics. Is there a way do this explicitly i.e. instead of creating an inner float with

\placefigure[force][ref1]{this is the caption }{\externalfigure[cow][width=3in,height=1in]}

could we create a non-floating version with something explicit like

\externalfigure[cow][width=3in,height=1in]
\addcaption[figure][ref1]{this is the caption }

Use a nested combination.

I was going to suggest such things...

Here is a case where a float is not being used as a floating object in
that we want to control placement through location=here or, better,
location=force. We do this as users for we want to produce a caption
as well as make an entry into the list.

However, floats have some limitations: for example they cannot usually
handle multiple pages (except for some table splits), nor can they take
\startcolumns \stopcolumns, and I am sure that there are others.

Does anyone have suggestions/ideas around these kinds of issues? Should
a float with location=force be treated any differently?

Another annoying issue with floats: \startplacefloat\stopplacefloat
initiates a paragraph break. If one refers to a float (figure or table)
somewhere in a long paragraph, one might like the float to be anchored
starting from that location. I achieve this using
\startpostponing [+0]
  \startplacefigure
  \stopplacefigure
\stoppostponing
but this does not always work well. In addition, this is not very
satisfying (as it makes for ugly source code). Also, one might want to
use location=right or location=left without using "hang" and counting
lines. Hans has repeated that floats are complicated beasts and such
features would interfere with paragraph building. OK (But dare I say
that LaTeX does not seem to have any problem with this.)

Alan

P.S. Would not the use of \startcombination\stopcombination be an
alternative to the placefigures within a table?

My motivation is different. If you have any macro in a table (or anything 
that requires multiple runs to get the size right) that uses a counter 
(e.g., enumeration), then the numbers will be off. That would not happen 
if a counter is frozen when trialtypesetting is on.

combinations only give regular grid. Sometimes you want an irregular grid. 
For example, the OP wanted

+------+------+
|      |      |
|      | Fig2 |
| Fig1 +------+
|      | Fig3 |
|      |      |
+------+------+

Such layouts are not possible using combinations.

depends a bit .. other mechanisms do a save, increment, restore, which 
better reflects the number to be rendered (otherwise you can get 
oscillating runs)

Skipped figure numbers

[Aidan Nichol]

I have been looking at various options for controlling how figures are placed on a page and based on answers to similar questions in this mailing list I  tried various options. The most flexible one seems to be using tables e.g.

\setupexternalfigures[location={default}]

\starttext

\placefigure[]{}{\externalfigure[hacker][height=1in]}

\startxtable[frame=off,align=low]
\startxrow
  \startxcell[ny=2]
      \placefigure[force][]{left twoup}{\externalfigure[mill][height=4in]}
   \stopxcell
   \startxcell
     \placefigure[force][]{the first}{\externalfigure[spider][height=1.5in]}
   \stopxcell
\stopxrow
\startxrow
  \startxcell
    \placefigure[force][]{the second}{\externalfigure[cow][height=1.5in]}
  \stopxcell
\stopxrow
\stopxtable

It seems to work well except that figure numbers are being skipped. In this example hacker=1 mill=8, spider=9 and cow=10.
Varying the contents of the table reveals that It is skipping two times the number of figures in the table.

Is this an invalid combination of features I’m using or am I doing something wrong?

The contents of a table are typeset multiple times to get an idea of the
height and width. Here is one option:

\useMPlibrary[dum]

\starttext

\bTABLE[frame=off,align=low]
\bTR
\bTD[ny=2]
      \placefigure[here,\iftrialtypesetting nonumber \fi]
                  []{left twoup}{\externalfigure[mill][width=2in,height=4in]}
\eTD
\bTD
      \placefigure[here,\iftrialtypesetting nonumber \fi]
                  []{the first}{\externalfigure[spider][width=2in,height=2in]}
\eTD
\eTR
\bTR
\bTD
      \placefigure[here,\iftrialtypesetting nonumber \fi]
