"javax.servlet.ServletException: text name must not be null" when subtitle =
null in DAY mode
---------------------------------------------------------------------------------------------
Key: MYFACES-887
URL: http://issues.apache.org/jira/browse/MYFACES-887
Project: MyFaces
Type: Bug
Components: Sandbox
Versions: 1.1.1
Reporter: Paul Spencer
When the schedule is in DAY mode, an entry with getSubtitle() == null causes
the following error returned
javax.faces.FacesException: text name must not be null
org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:421)
org.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView(JspViewHandlerImpl.java:234)
org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:352)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:107)
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)
A portion of the stack trace from the log file is below, but I believe the
resolution is to only write the subtitle if it is not null in
ScheduleDetailedDayRenderer.java around line 505.
>From localhost.log
SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException: text name must not be null
