Created attachment 95305 [details]
Sample file including some of the form controls.
Currently LibreOffice Writer cannot export any form controls to docx. format while it can export to doc and odt.
I've created a sample document and attached. Saving as docx then opening it either with LibreOffice Writer or Microsoft word will result an empty doc.
There are some bug reports already reported but for specific form controls like text box, radio button etc, but i can say that none of these form controls can be exported.
Form controls are very important in corporate usage, and such problem has a high priority for such users.
