Hello again:
I have a jsp code like this:
<div>
<s:select name="type" list="#application.types" label="Tipo contenido:"
/>
<div>
Where I populate a select from the a ServletContext attribute:
public class UserDataListener implements HttpSessionAttributeListener,
ServletContextListener {
...
public void contextInitialized(ServletContextEvent sce) {
ServletContext servletContext = sce.getServletContext();
types = new ArrayList(3);
types.add(Constants.UNO);
types.add(Constants.DOS);
types.add(Constants.TRES);
servletContext.setAttribute("types", types);
}
...
}
Sometimes, I found a message like "Caught an exception while evaluating
expression '#application.types": java.lang.NullPointException"
I don't know what i am doing wrong (i copied the code from a struts 2 manual
:confused: )
Any clue?
I also tried #application['types'], and still nothing.
Thanks.
