Bug in placeformula with framed text

Hi Hans, It seems that there is a bug in the latest beta (ConTeXt vesion: 2016.07.01 16:28) when using \placeformula with a framed text environment. The numbers for the formulas are placed incorrectly, on the left as well as on the right. Also, as one may see in the example below the numbering of the formulas begins at 2 instead of 1 at the first instance, and at it continues at 6 instead of 4 in the second instance. Below is an example (sorry if it is not absolutely minimal: I ran into this bug when updating a lecture notes which uses a left frame around \proclaim stuff). I attach the PDF showing the problem. I wonder whether this is related to the new features introduced recently for math frames. The code gives correct result with ConTeXt version 2015.05.18 12:26 from TeXLive 2015). Best regards: OK %%% begin bug-framed.tex \defineframedtext[ProclaimFramed] [width=\textwidth, frame=off, leftframe=on, framecolor=darkred, rulethickness=2pt, offset=0pt, loffset=4pt, roffset=4pt, ] \defineenumeration[proclaim] [text=, before={\startProclaimFramed}, after={\stopProclaimFramed}, style=slanted, title=yes, titleleft=, titleright={.}, alternative=hanging, number=no, width=fit, right={~}, ] \definemathalignment[Lgather][n=1,align=left] \starttext \setupformulas[location=left] \startproclaim{Some elementary properties of Landau notations} Let $(a_{n})_{n}$ and $(b_{n})_{n}$, as well as $(u_{n})_{n}$ and $(v_{n})_{n}$, be sequences of complex numbers.

Hi Hans, Thanks a lot for having fixed the issue I was reporting. Unfortunately I found another issue related to placeformula and alignment in math mode. In the following example the use of \startalign in a \placeformula triggers a weird behavior in the sense that the following instance of \startformula gets also a number, even though one does not issue a \placeformula command. Moreover the number is placed incorrectly. In the resulting PDF I am attaching, please look at the numbers (4) and (8) placed incorrectly (and they are not wanted neither…). When one removes the \placeformula command, the result is correct.
