Hello;
I also depend on this functionality to enforce data entry. Would be
painful for it to be removed.

Hi,
in the past (until WO 5.4) I often have used a WOTextField with a
formatter to prevent errors like this:
"java.lang.IllegalArgumentException: While trying to invoke the set
method "public void com.cx.harow.eos._ArztFolgedokLeistung
$StorageClass.setAnzahl(java.lang.Short)" on an object of type
com.cx.harow.arzt.dokumente.ArztFolgedokumentationContext
$TempFolgedokLeistung we received an argument of type
java.lang.String. This often happens if you forget to use a
formatter."
When a value was invalid the formatter did not set an invalid value
in my objects.
Now, in WO 5.4 this is no longer true. When the formatter fails to
parse a string it still gets pushed into the target object. As this
is documented is must somehow be considered "expected" behavior.
Unfortunately this breaks all our apps, as no class handles those
invalid strings.
Whoa! Where is this documented? I also depend on this.

What is the best way to restore a sane behavior in WO 5.4? Do I
have to write validate...-Methods for every class, that gets
formatted values and drop those strings? Does WONDER have a fix for
this?
Thanks,
Ralf
