[JBoss Seam] - Page events produce 'No active event context' exception
by evanzeng
I want to use the following 'index.html' and 'pages.xml' to redirect to a page 'home.xhtml' which again redirect to a customized homepage.
index.html:
| <html>
| <head>
| <meta http-equiv="Refresh" content="0; URL=default.jsf">
| </head>
| </html>
|
pages.xml:
| <pages>
| <page view-id="/default.xhtml" action="#{homepage.redirect}" />
| </pages>
|
home.xhtml:
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
| "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
| <html xmlns="http://www.w3.org/1999/xhtml">
| <head>
| <meta http-equiv="Refresh" content="0; URL=#{homepage.homepage}" />
| </head>
| </html>
|
The 'homepage' component is defined like the following:
| @Name("homepage")
| @Stateful
| public class HomepageBean implements Homepage {
|
| private String homepage;
|
| @In
| private GlobalSettings globalSettings;
|
| public String redirect() {
| HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance()
| .getExternalContext().getRequest();
|
| if (request.getRemoteUser() == null) {
| homepage = globalSettings.getSiteHomepage();
| return "homepage";
| }
|
| ......
|
| }
|
| public String getHomepage() {
| return homepage;
| }
|
| }
|
And in my faces-config.xml there is a navigation rule:
| <navigation-case>
| <from-outcome>homepage</from-outcome>
| <to-view-id>/home.xhtml</to-view-id>
| <redirect />
| </navigation-case>
|
Everything works fine but the Concole produes the following exception:
