Hi,
I have reconverted my apps to the new (eclipse 3.1) resource bundles. I also
convert my own helper method which calls "MessageFormat.format" to the new
NLS.bind (see description under
http://www.eclipse.org/eclipse/platform-core/documents/3.1/m essage_bundles.html).
Now I get a "java.lang.IllegalArgumentException" when I call the method
NLS.bind. This is due to the fact, that NLS.bind doesn't use
MessageFormat.format and therefore doesn't understand my format definitions
in the string (example: "Bytes trasferred: {0,number,###,###,###,###}").
Is this a bug or a feature? Why NLS.bind doesn't call MessageFormat.format?
Can anybody help me?
Bye Stefan

NLS.bind is *no* replacement for MessageFormat.format, this is a
well-documented fact of the NLS class:
"[..]The #bind methods perform string substitution and should be
considered a convenience and not a full substitute replacement for
MessageFormat#format method calls
[..]
"Clients who wish to use the full substitution power of the
MessageFormat class should call that class directly and not use these
#bind methods."
Btw, you can easily combine both worlds by transferring the intermediate
result of your own MessageFormat.format call as further argument of
NLS.bind, if necessary.
