You need to install 0.5-12, where the newly 'defined' parameters 
(defined by the ":=" operator) are standardized too (just like the other 
parameters). This version is not on CRAN yet, but you can install it by 
typing in R:

install.packages("lavaan", repos="http://www.da.ugent.be", type="source")
