[jira] [Commented] (TRINIDAD-2126) convertdatetime fails with datestyle=full, th_th or ja_jp_jp locale

["Yee-Wah Lee (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/TRINIDAD-2126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13082748#comment-13082748 ] 

Yee-Wah Lee commented on TRINIDAD-2126:
---------------------------------------

Debugging, the era string used in the LocaleElements_th.js file do not match the strings used by SimpleDateFormat. Thus the client converter fails to parse the eras.

>From discussion with Java folks it's known that DateFormatSymbols#getEras returns a pair of strings for Gregorian calendar AD and BC even if locale is set to
Thai or Japanese Imperial calendar. They think it's by design but need raise a document bug.

To obtain eras for non Gregorian calendars, one need to use Calendar class like following;

   Calendar c = Calendar.getInstance(th);
   String era = c.getDisplayName(Calendar.ERA, Calendar.LONG, th);
   System.out.println("Calendar era: " + era);

 or

   Map<String, Integer> eras = c.getDisplayNames(Calendar.ERA, Calendar.LONG,
th);
   for ( String key : eras.keySet())
       System.out.println("Calendar eras: " + key);

> Run the page, and modify the date slightly so that it is still valid. Tab
> off, get an error about the message not being in the correct format, though
> the format itself did not change and the date is semantically valid.
