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.
WOTextField:
formatter
[...]
If a user enters an “unformattable” value, WOTextField passes the
invalid value through, allowing you to send back an error page that
shows the invalid value.
[...]
Uh oh. Are you saying that it no longer calls
void
validationFailedWithException(Throwable t, Object value, String keyPath)
Called when an Enterprise Object or formatter failed
validation during an assignment.
When the format operation fails? That is a bug. Or a totally
unacceptable API change.
