I am searching since several days  now .... tomorow y need a solution :-(

I want to rotate two lines with:

\starttext
   \bTABLE
      \bTR
          \bTD{\rotate[rotation=90]{first line\crlf second line}}\eTD
      \eTR
   \eTABLE
\stoptext


but instead of: (rotated 90°)
   first line
   second line

I get:
   first linesecond line


Help. Please.

   \bTABLE
      \bTR
          \bTD[rightframe=off]{\rotate[rotation=90]{first line}}\eTD
          \bTD[leftframe=off]{\rotate[rotation=90]{second line}}\eTD
\bTD{and some text in the next column}\eTD
