Yes, you are correct.  You can probably guess which one I have been =
looking at lately.  :-)

I think the only way would be to make your own NSNumberFormatter in your =
own com.webobjects.foundation package and get it to load first on the =
classpath (Wonder does this for ERXExtensions).

Also, formatters are NOT threadsafe so having them shared from the =
application instance will lead to problems in times of high concurrency. =
 They should be cached on the session or lower.

I dive into that, isn't there a way to say globally for an entire WO =

a number, consider '.' and ',' equal"? That would help a lot.
