Regression with \doboundtext in \writetolist

The following example works with older versions of ConTeXt, such as the 
version from 20150325 in my repository. It fails with TL15 and later, 
including the current standalone beta.

    % macros=mkvi
    \setwidthof {99}\to\IDWidth\relax
    \def\STWidth{\dimexpr\textwidth-\IDWidth+1cm}
    \definelist[OList]
    \setuplist
    [OList][criterium=all,alternative=c,pagecommand=\gobbleoneargument]

    \starttexdefinition OLister #ID#String
    {\writetolist[OList]{}{\hbox{\simplealignedbox{\IDWidth}{left}{#ID\quad}
    {\doboundtext{#String}{\STWidth}{…}}}}}
    \stoptexdefinition

    \starttext
    \OLister1{Some list testing text xxx xxx xxx xxx xxx xxx xxx xxx xxx
    xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx}
    \OLister2{Yet another list testing text xxx xxx xxx xxx xxx xxx xxx
    xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx}
    \OLister3{A list testing text xxx xxx xxx xxx xxx xxx xxx xxx xxx
    xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx}
    \OLister4{Different list testing text xxx xxx xxx xxx xxx xxx xxx
    xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx}
    \subject{List half width}
    \startcolumns[n=2]
    \placelist[OList]
    \stopcolumns
    \stoptext

With the 20150325 ConTeXt, there are .tuc file entries like:

        ["second"]="\\hbox {\\simplealignedbox {\\IDWidth
    }{left}{2\\quad }{\\doboundtext {Yet another list testing text xxx
    xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
    xxx}{\\STWidth }{…}}}",

but with more recent versions, the corresponding entry is:

        ["second"]="\\hbox {\\simplealignedbox {12.6pt}{left}{2\\quad
    }{\\hbox {\\setbox \\scratchbox \\hbox {Yet another list testing
    text xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
    xxx xxx}\\scratchdimen \\dimexpr \\textwidth -12.6pt+1cm\\relax
    \\box \\scratchbox }}}",

Yes, expansion needs to be delayed to get the current dimension when the 
list is placed. My error—thank you for the correction. But the 
regression is not resolved. The .tuc file now contains:

    ["second"]="\\hbox {\\simplealignedbox {12.6pt}{left}{2\\quad
    }{\\hbox {\\setbox \\scratchbox \\hbox {Yet another list testing
    text xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
    xxx xxx}\\scratchdimen \\STWidth \\relax \\box \\scratchbox }}}",

Still no mention of dobounded text is carried into the list.

Is \limitatetext a option for you because unlike \doboundtext the 
command is unexpandable?

\starttext

\doboundtext {Thus, I came to the conclusion that the designer of a new 
system ...}{.5\textwidth}{...}

\limitatetext{Thus, I came to the conclusion that the designer of a new 
system ...}{.5\textwidth}{...}

\stoptext

Is it an option of which I am aware, yes. Do I desire to use it, no. 
Will I use it? Perhaps, if \doboundtext cannot be repaired. The 
resulting page with \limitatetext has large rivers of white on the page.

But more likely I will look for a hack to use \doboundtext to trim the 
text before writing it to the list, even though it loses the flexibility 
of computing the width dynamically.

Can you point to what changed between the 20150325 version and TL15 to 
break this?

Adding \noexpand before \doboundtext should work.

Indeed, it does. Thank you.
