Matthias,
I must be missing something. Adam
org.apache.myfaces.trinidad.convert.NumberConverter.getAsObject() to convert
the spaces that the user might have typed in to the non-breaking spaces that
the NumberFormat expects if the grouping character is a non-breaking space.
<tr:inputText value="#{validate.currency}"
id="outputText1">
<tr:convertNumber locale="fr_FR" type="currency"/>
</tr:inputText>
The rendered output is "12 345,68 €", which is fine.
When re-submitting this value, you'll see an converter-error-msg, that
the format is wrong.
That is because:
1. the groupingSeparator() in fr_FR is '\u00a0'
2. therefore the " " between 2 and 3 AND 8 and € is replaced by '\u00a0'.
I don't understand why this fails. Isn't the code Adam added explicitly
designed to make this work, by replacing the spaces with non-breaking spaces
before feeding the String to be converted to the NumberFormat?

I looked at this again this morning:
A simple Java-test fails and shows why:
Doing this:
String va = "12 345,68 €";
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.FRANCE);
Number n = (Number) nf.parseObject(va);
and you'll see that n is NULL.
Why?
So, here it is:
the String va contains to blanks (" "), which are between 2 and 3, and
between 8 and € as well.
In fr_FR, however, the *grouping separator * is not " ", but it is a
special char for blank (\u00a0).
So, my little test will pass, when the first BLANK is replaced by the
special char...
I thought, that the NumberFormat actually does parse the object for me.
Looks like (for fr_FR) I have to create a *custom parser*... Which is odd,
IMO
Now, do this:
String va1 = "12 345,68 €";
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.FRANCE);
String va2 = nf.format(12345.68));
System.out.println(va1.equals(va2));
and you see, what the issue is...
Anyway, anyone that has an idea on that one?
Thx!

for fixing Trinidad-202 ([1] (was done during incubation)), we added
these lines (and some other)
DecimalFormat df = (DecimalFormat)fmt;
DecimalFormatSymbols dfs = df.getDecimalFormatSymbols();
if (dfs.getGroupingSeparator() == '\u00a0')
value = value.replace(' ', '\u00a0');
So far, so good.
But that causes issues, when running in "fr_FR" locale, like:
<tr:inputText value="#{validate.currency}"
id="outputText1">
<tr:convertNumber locale="fr_FR" type="currency"/>
</tr:inputText>
The rendered output is "12 345,68 €", which is fine.

the later is the issue, and the conversion fails.
Any ideas ?
