[opencms-dev] programatically determine which locale is currently being edited

[Paul-Inge Flakstad]

Greetings again Marc, Achim 

I did a quick rewrite (see below) of the source code provided in the OpenCms 7 development book, and I'm glad to inform that Achim's tip did the trick. :) The select options are now being built using the editor's currently selected locale.

Many, many thanks to Achim for submitting this example code!

Best regards,
Paul


 Source changes
================

I_WidgetSelectSource: 

Changed 
	getValues(CmsObject cms) 
to 
	getValues(CmsObject cms, I_CmsWidgetParameter param)

---------------

Changed all classes implementing I_WidgetSelectSource to reflect the above change.

---------------

CmsCustomSourceSelectWidget:

Changed 
	getSelectOptionData(CmsObject cms) 
to 
	getSelectOptionData(CmsObject cms, I_CmsWidgetParameter param)

---------------

ContentFieldListDS#getValues(CmsObject cms, I_CmsWidgetParameter param):

Changed the line
	List lVals = content.getValues(m_strFieldname, cms.getRequestContext().getLocale());
Into this snippet
	// Get the editor's current locale (or fallback to default locale)
      Locale defaultLocale = OpenCms.getLocaleManager().getDefaultLocale();
      Locale dialogContentLocale = ((I_CmsXmlContentValue)param).getLocale();
      Locale locale = null == dialogContentLocale ? defaultLocale : dialogContentLocale;
      // Get the values using the specified fieldname and locale
      List lVals = content.getValues(m_strFieldname, locale);

---------------

That's it - hopefully I didn't forget anything. :)
