when you choose the array-form, all formulas are written in textmode,
so it's not possible to write sum- or integral-symbols with indexes
over or under the sum or integral. All indexes are super- or subscripts.
This is a latex mode and not specific to lyx.
But it's not correct in lyx, because the indexes are over or under the
symbols.

in this mode (eqnarray) latex defines the left and the right part
as independent formulas and the middle one as textformula. This
means, that you can write sums and integrals with indexes over or
under the symbol. This is not possible for the middle part.
In this mode lyx shows all formulas as independent equations, which
is not right!
Try this: Create a displayed equation, hit C-Return and than type a
sum with an index over and under the symbol. Copy this one in the other
two parts of the formula. LyX makes no differences, but ps-view shows
the right latex-definition: the left and the right part are the
same and the middle one is in textmode like the array-environment.
