Hans,
I have the following sample:
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=1em]
\definefield[x][signature]
\field[x]
\stopTEXpage
\stoptext
And for the signature two widgets are generated (I include object 7 to
make sense of the kids in objet 8):
7 0 obj
[ 9 0 R ]
endobj
8 0 obj

When Acrobat XI (Win, just in case) signs the document, both widgets are
merged into one:

Would it be possible to generate only one annotation widget for the
signature?
Only if one beforehand would indicate that there are no more possible
kids (we don't want to keep that info as yet another bit of multipass
data) which would be yet another hard to explain (undocumented feature).
The current approach is afaik valid (and it's already hard enough to get
these widgets robust over pdf / acrobat versions). It would also make
the code messier (nwo we clearly separate parent and instance, then we
have an extra hybrid form which duplicates the code). So, what is the
benefit? Saving a few bytes hardly matters here.
