Doh!
I have figured out a workaround, though, which is to create the inner
matrix somewhere else and then pasting it into the enclosing cell,

that procedure is not exactly convenient. Is there a saner way?
No, I am afraid. There is no reason to not allow an array inside an
array.
LaTeX allows this, so it is wrong to disallow it in LyX. Please file a
bug report at http://bugzilla.lyx.org/

Hi,
there is another way, if you're willing to use the \matrix or
\pmatrix commands provided by AMSmath. If you're in a math
environment and type \pmatrix, a matrix is created whose dimensions
you can change using the "Edit>Rows&Columns" menu (it's not
accessible if you're not in a matrix environment). Now if you want to
create a block (or "sub-matrix") inside that matrix, just type
\pmatrix again, and go through the same dimensioning steps. Type
\matrix to get an "array" without surrounding brackets, or try
\bmatrix, \Bmatrix, \vmatrix, \Vmatrix. This is described in the
AMSmath documentation, but also in Uwe Stöhr's excellent LyX math
manual (which I only have in German - is it out in English yet?).
