Yee-Wah Lee commented on TRINIDAD-2133:
---------------------------------------
The convertDateTime uses the javascript Date APIs to create/validate the date,
however, JS still uses GregorianCalendar
http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262%20edition%205.1,%20June%202011.pdf
To support this scenario, the convertDateTime peer would have to add/subtract
the year offset when displaying/parsing.

> Key: TRINIDAD-2133
> URL: https://issues.apache.org/jira/browse/TRINIDAD-2133
> Project: MyFaces Trinidad
> Issue Type: Improvement
> Components: Components
> Affects Versions: 2.0.0
> Reporter: Yee-Wah Lee
> Priority: Minor
>
> 1. Create and run the following jspx
> <tr:inputText is d="dt" autoSubmit="true" value="#{input.date}">
> <tr:convertDateTime locale="th_TH"/>
> </tr:inputText>
> <tr:outputText value="#{input.date}" partialTriggers="dt">
> <tr:convertDateTime locale="en_US"/>
> </tr:outputText>
> 2. The page will display the date using the Thai Buddhist Calendar, then the
> date in US format (which uses GregorianCalendar on the server side). The Thai
> Buddhist calendar is offset by 543 years from the Gregorain, e.g. the
> inputText shows 22/8/2554 and the outputText shows 8/22/2011 .
> 3. Update the inputText to 29/2/2555 which is equivalent to 2/29/2012
> Gregorian, a valid date. However this gives an error, "Enter a valid date or
> time".
