Description

This is not only a bug in Trinidad... It is mainly an issue in the core date_time_converter as well:

<h:form>
<h:messages/>
<h:inputText value="#

{input.date}

" immediate="true">
<f:convertDateTime type="both" timeStyle="full"
timeZone="America/New_York"
pattern="dd.MM.yyyy HH:mm' Uhr '"
locale="de"
/>
</h:inputText>
<h:commandButton value="Submit" type="submit"/>
</h:form>

Note that the pattern is like this: dd.MM.yyyy HH:mm' Uhr '
After the word "Uhr" there is an empty space (required by the pattern).

Now when you enter this String "30.06.09 12:11 Uhr " (notice the empty String at the end),
we run into the problem, that the spec wants the converter to trim leading/trailing whitespaces before proceeding. Makes sense....
but gives us a (neat) error.

See this JavaDoc section:
http://java.sun.com/javaee/javaserverfaces/1.2_MR1/docs/api/javax/faces/convert/DateTimeConverter.html

<snip>
If the specified String is null, return a null. Otherwise, trim leading and trailing whitespace before proceeding.
</snip>

However, when the pattern requires an empty space at the end, we (the converter) should honor that...

possible change in the converter code (after the trim() has been called):
if(pattern.endsWith(" '"))

{ value += " "; }
