question about bar lines

[Alex Jones]

I am having a problem with bar lines, if I put the following around a staff 
break

\bar "||"
\break

\bar "|:" 

I get the repeat sign on the start of the staff, but not the double bar on the 
end of the previous staff.

I am using partial bars before and after the break, but through 
experimentation, this doesn't seem to change much.  If I remove the open 
repeat, the double bar appears on the first staff.

Anyone have any ideas what I'm doing wrong?

Thanks very much!
