Summary: Support custom negative prefix and suffix on
af:convertNumber
Key: TRINIDAD-2496
URL: https://issues.apache.org/jira/browse/TRINIDAD-2496
Project: MyFaces Trinidad
Issue Type: Improvement
Components: Components
Reporter: Ashwin Prabhu
This is an enhancement request of af:convertNumber (converter class is
NumberConverter) to support additional conversion function for negative
numbers.
It is expected to enhance af:convertNumber (converter class is
NumberConverter) to support the following:
1. new attribute of negativePrefix and negativeSuffix
2. parsing/formatting support in both client and server side using negative
prefix/suffix
--------------------------------------------------------------------------------------
Problem description:
Financial applications sometimes require that negative numbers be displayed
within () instead of the usual -ve prefix. Ex: -1234 as (1234).
Currently Trinidad based applications can achieve this by specifying a pattern
on the number converter, like for example "#;(#)". This works, but the caveat
is that patterns are not processed by the client converter. So essentially to
parse and format numbers, the application must wait until the input is
eventually submitted to the server or perform a auto-submit to expedite the
validation. Performing auto-submit to validate the input for converter pattern
compliance is noticeably slow and wastes a server round trip. So the request is
to enhance the client converter to parse/format numbers with suffix/prefix on
the client and this should work for all types: number, percent,
currency(already works).
