st: Missing values error in -xtabond2-

I'm having a slight problem with using David Roodman's -xtabond2-
(downloadable from SSC), thus:

. tsset pano edyear
       panel variable:  pano, 1 to 659
        time variable:  edyear, 1976 to 1992, but with gaps

. xtabond2 edconpc ledconpc ed2-ed13 edpollch lagconch laglabch lagldmch
clmargin cdmargin conplace edenp class if edmarker==1, gmm(l3edconpc)
Missing values in time variable (edyear).

I should point out, if necessary, that ED2 to ED13 are all time dummies.
The rest are continuous covariates.

Using -tsfill- after -tsset- made no difference. I thought one could fit
Arellano-Bond models with unbalanced panels? Any help duly appreciated.
