My custom view handler works seamless with JSF navigation and Seam pageflow and
forces templates names in the form of name_loc.xhtml, for example
register_en.xhtml, register_de.xhtml Etc.
Hope that this won't cause any complications in future versions of Faces or
Seam.
Here the details:
1) In faces-config.xml (for example):
<application>
| <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
| <view-handler>com.mycompany.util.LocaleViewHandler</view-handler>
| <message-bundle>messages</message-bundle>
| <locale-config>
| <default-locale>en</default-locale>
| <supported-locale>en</supported-locale>
| <supported-locale>de</supported-locale>
| <supported-locale>ru</supported-locale>
| </locale-config>
| </application>
2) Implement LocaleViewHandler class (some additional methods have to be
implemented, but they should simply wrap the base class functionality)
import javax.faces.application.ViewHandler;
| ...
| public class LocaleViewHandler extends ViewHandler
| {
| private ViewHandler base;
| private static final String separator = "_";
| private static final String actionExtension = ".seam";
|
| public LocaleViewHandler(ViewHandler base)
| {
| super();
| this.base = base;
| }
|
| public String getActionURL(FacesContext context, String viewId)
| {
| StringBuilder newActionURL = null;
| String actionURL = this.base.getActionURL(context, viewId);
| StringBuilder localeSuffix = new StringBuilder(separator);
| localeSuffix.append(LocaleSelector.instance().getLocaleString());
| StringBuilder localizedEnd = new StringBuilder(localeSuffix);
| localizedEnd.append(actionExtension);
| int pointPosition = actionURL.indexOf(actionExtension);
| if (pointPosition != -1 &&
actionURL.indexOf(localizedEnd.toString()) == -1)
| {
| newActionURL = new StringBuilder(actionURL.substring(0,
pointPosition));
| newActionURL.append(localizedEnd);
| return newActionURL.toString();
| } else
| {
| return actionURL;
| }
| }
| ...
| }
