Changing String default converter
JSF by default assign empty string at backing bean properties when a form is
sent. I want to override that with a custom converter. My problem is my
converter is never called. This is the code at faces-config.xml:
<converter>
<converter-for-class>java.lang.String</converter-for-class>
<converter-class>
myPackage.NullableStringConverter
</converter-class>
</converter>
If I set breakpoints inside getAsObject or getAsString I see it doesn't
stops there. What am I doing wrong?

Yes.
Or depending on what you're doing, there might be other ways to handle it.
For most of my needs, I only needed null rather than empty string when
saving data to a database, so I changed my database layer software to
perform the empty-string-to-null conversion at that point.
For the few other places I needed to check (business logic), I checked
against both null and empty string.

So I assume I must wait till myfaces-1.2.something :-\ Till then I'll use
explicit converter selection...
Thank you very much!

Registered "automatic" by-class String (and Object) converters are not
allowed in JSF 1.1.
It's been fixed for JSF 1.2.
