Hello,
i try to use the Result Annotations in my new Project, this works fine for me.
But when I try to use parameters I become an Exception.
Config:
@Namespace(value="/")
@Results( {
@Result(value = "myresult.action", type =
ServletActionRedirectResult.class, params={"ID","${ID}"}),
@Result(value = "/pages/search.jsp", name="input")
})
public class Search extends BaseSupport
In the log I found following messages:
DEBUG (org.apache.struts2.config.ClasspathPackageProvider:58) -
ClasspathPackageProvider: Processing class de.geppert.actions.Search
DEBUG (org.apache.struts2.config.ClasspathPackageProvider:58) - Adding
parmeter[ID:${ID}] to result.
this looks fine but I when I use this Action It returned a NullPointerException
and following log messages:
ERROR (com.opensymphony.xwork2.DefaultActionInvocation:28) - There was an
exception while instantiating the result of type
org.apache.struts2.dispatcher.ServletActionRedirectResult
Caught OgnlException while setting property 'ID' on type

Can anybody resolve my problem? I think my configuration has no errors,
because my Actions without parameters work fine.
