st: Estimation Storage with XTPQML

[milet <emmanuel.milet@cepii.fr>]

Hello,
I use Stata10 and have problems when I try to store estimations after a 
xtpqml procedure.
Stata estimates properly the coefficients, and then calculates the 
robust standard errors, but when it comes to store the estimation, I get 
the following error message:
"last estimation results not found, nothing to store".
r(301);
Is it because Stata only keeps in memory the estimation with robust 
standard errors, and does not consider it as an estimation (thus not 
able to store it?).
Many thanks.
