Subject [jira] [Created] (TRINIDAD-2533) TrNumberFormat doesn't parse native Numbers without Currency
Date Wed, 10 Feb 2016 16:59:18 GMT
Falco Wockenfuß created TRINIDAD-2533:

             Summary: TrNumberFormat doesn't parse native Numbers without Currency
                 Key: TRINIDAD-2533
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions: 2.0.0-beta-2
         Environment: Oracle ADF
            Reporter: Falco Wockenfuß

If you enter a Number in a Currency-Field with a decimal separator (other than ".") and without
trailing currency symbol you get a parse Error.

Test Case - Type in JS Console:
var tr = new TrNumberConverter( null, "currency", "de_DE" );
tr.getAsObject( "20,50" ); // Parse Error
tr.getAsObject( "20,50 €" ); // Working
tr.getAsObject( "20" ); // Working

The Method TrNumberFormat.prototype.removePrefixAndSuffix will fail, if not both matching
Prefix and Suffix for Positive or Negative are present. If only one of both is present an
exception is thrown and parsing fails.
Since the Prefix for positive Currency is "" (the empty string) it will always match and try
to find the matching suffix "€" or fail.

In the case of an exception the default parseFloat is used as a fallback, which works for
default english notation, so plain Numbers and using the dot as a decimal separator will work.

Expected Behaviour and proposed Fix:
Entering a locale Numberformat without Currency Symbol should be parsed without giving an
error. The removePrefixAndSuffix Method should be more lenient and also accept input without
currency suffix.
