Renaming fails on composite Xdf if rownames present

[hongooi73]

# explicitly create a composite Xdf (directory)
mtc <- RxXdfData("mtcarsc", createCompositeSet=TRUE)
rxDataStep(mtcars, mtc, overwrite=TRUE)

names(mtc)[1] <- "mpg2"
# In 'UpdateMetaInfo()' the two headers have different numbers of variables: 12 vs 11.
# Error in doTryCatch(return(expr), name, parentenv, handler) : 
#   In 'UpdateMetaInfo()' the two headers have different numbers of variables: 12 vs 11.

This happens if dataset has row names. Following works:

irc <- RxXdfData("misc/irisc", createComposite=TRUE)
rxDataStep(iris, irc)
names(irc)[1] <- "sl"
