If I understand correctly the \midrule is moved to the next page beacuse it is 
after \tabularnewline, and it is placed below the header which must be on top. 
Is this correct? Or is it moved because there is not enough room for it on the 
page?

But how can I prevent this? When I make the table in lyx/latex I cannot predict 
how many
rows will fit a page.  I dont't see either how I can fix this. If I remove the 
bottom rule from row I, the duplicated rules won't show above row J. But I 
still won't have the rule below row I. How can I make the bottom rule stuck to 
row I?

Looking at the source I see that lyx specifies the first two rows as header; 
\endhead is inserted after row A. How can I set lyx to use only the first row 
as header?

if I try to explain this in the context of your example, and how to fix the
problems you outlined. I will answer them out of order, though so I hope
you don't mind.

2) LyX sets the rows as headers that you tell it to. This is done by going
into a row, and right-clicking. You can see the row's settings under "Row
Settings" in the longtable tab. In your case, you had both the first and
second rows set as header rows. When I downloaded your example, and
deselected the header row checkbox for the second row, it only uses the
first row as a header. Problem 2 solved.

3) Once we understand the above, that should help here. The reason you have
two separator lines is because on the header row, you have the row set to
have a border below the row. So, everywhere the header row appears, it sets
a border below. That's why you see a border below for that, and also the
border for the row it was displaying anyway. So, remove the border below on
the the header row, and only use a border above on your other rows, and
that will fix things.

1) This one is the most complicated, and it has to do with something about
how the rows behave. For some reason which makes no sense to me, the page
breaking behaves such that a row may print the contents on one page, but
the border below on another (or print the border above on the previous
page, but the contents on the next). Fortunately, this (strange) behavior
can be controlled by manually telling the table where to break pages. This
is done by right-clicking in a row, and within the table settings,
selecting the checkbox by "Page break on current row." That makes the
behavior predictable, which is nice. Then, you have to put two borders, one
below the current row, and one above the next (so there is a separation
between the row header and the first row that appears under that on the
page).

There are other combinations of specifying where the cell borders go to get
what you want, but once one understands how LyX and longtable treat things,
it becomes possible.

Please see attached files for revised LyX input and .pdf output...produced
by LyX 2.0.8.1 in Linux Mint 17.1.

I hope this helps...I learned most of it by examining the longtable in
LyX's Embedded Objects manual, and experimenting with the settings.
