I extend TableDecorator for different sorting that what it is see in the column. The content of cells for this column must be internationalizated:

For examle a method:

public String getListaComenzi3()
{
VizualizareComenzi lObject= (VizualizareComenzi)getCurrentRowObject();
int lIndex= getListIndex();
String sar ="";
if(lObject.getStareFactura().equals("2"))
sar = "<a href='/Festino/vizualizeazaFactura.do?comanda_id=" + lObject.getId()+ "&client_id=" + lObject.getCliId() + "' > " +
"<img src='images/check.gif' alt='Visualizza fattura' border='0'>" +
" </a>";
return sar;
}

In this case the "alt" must be language dependent but I dont have acces to the current locale.

Do you see a method to have acces to Struts localization in TableDecorator.

Or another method for internationalize in this case (I need Struts localization , not request)???

Thanks!!!

Hi,

in a TableDecorator you have access to the PageContext (getPageContext())

Struts leaves the current users Locale in the session under Globals.LOCALE_KEY (Globals is in package org.apache.struts). Some thing along the lines of:

Locale loc = (Locale)getPageContext().findAttribute(Globals.LOCALE_KEY) ;

Hope this helps.

Thanks a lot!!!

Now I optain the Locale, but I must find a way to optain a reference to my struts resource messages. Is a easy way to do this in TableDecorator???

there is some new stuff in display tag that I not very familar to do with pluging different i18n provides in to it.

The simplest solution for you (see that you're using struts anyway) is to use the TagUtils.message() method in org.apache.struts.taglib.

From MessageTag.doStart(){

        String message =
            TagUtils.getInstance().message(
                pageContext,
                this.bundle,
                this.localeKey,
                key,
                args);
}

or a even quicker/simplier way is to get the MessageResources is
getPageContent().findAttribute(Globals.MESSAGE_KEY);

Note this should give you the default messages, which may not be what you want (struts modules and all)

I haven't heard anything from Olaru on this so I guess somebody needs to close this issue for him.

The same desire localization also exists for columns (~~DISPL-204~~), however, since there, the application-programmer-provided class does not extend an existing displaytag class, but only implement an interface, the solution is not going to be as easy as here

pageContext is already available in tableDecorators, as explained in comments, closing
