ServletActionRedirectResult issue
Hi,
When I try to configure un ServletActionRedirectResult i obtain
Caused by:
java.lang.NullPointerException
at org.apache.struts2.dispatcher.mapper.DefaultActionMapper.getUriFromActionMapping(DefaultActionMapper.java:466)
at org.apache.struts2.dispatcher.ServletActionRedirectResult.execute(ServletActionRedirectResult.java:184)
at com.opensymphony.xwork2.DefaultActionInvocation.executeResult(DefaultActionInvocation.java:348)
using
@Result(name="success",value="findAllTables",params={"namespace","/tables","eid","${eid}","etid","${etid}"},type=
ServletActionRedirectResult.class)
public class CreateTableAction extends BaseAction {
private Long eid;
private Long etid;
+ getters / setters
BUT using
@Result(name="success",value="findAllTables",params={"namespace","/tables","eid","${eid}","etid7777WHATEVER","${etid}"},type=
ServletActionRedirectResult.class)
works fine
maybe a problem or bug in the implementation
Regards

Oh, I'm sorry; I read it backwards (I thought the wrong parameter didn't work
:)

Thanks Dave for the reply,
If i put the name "etid" an exception is thrown
If i put a larger parameter "whateverparametername" or simply "_" as
parameter name the redirect works fine, i know it's sounds weird
I thought that it the bug could come if the params attribute was a hash but
looking at the implementation i saw that is a String[]
(i have not investigated deeply if behind there is a hashmap)
Here is the action code
@Result(name="success",value="/jsp/tables/findAllTablesRedirect.jsp", type=
ServletDispatcherResult.class) // this is the fix
/**
* not working annotation
*
*
@Result(name="success",value="findAllTables",params={"namespace","/tables","eid","${eid}","etid","${etid}"},type=
ServletActionRedirectResult.class) // this not work
*
@Result(name="success",value="findAllTables",params={"namespace","/tables","eid","${eid}","etid777","${etid}"},type=
ServletActionRedirectResult.class) // this works (i can't understand why)
**/
public class CreateTableAction extends BaseAction {
private Long eid;
private Long etid;
@Override
public String execute() throws Exception {
Model.createTable(eid,etid);
return SUCCESS;
}
public Long getEid() {
return eid;
}
public void setEid(Long eid) {
this.eid = eid;
}
public Long getEtid() {
return etid;
}
public void setEtid(Long etid) {
this.etid = etid;
}
}

I'm not sure I understand; in your annotation example you deliberately
provide a wrongly-named parameter, right? Why?

My workaround
@Result(name="success",value="/jsp/tables/findAllTablesRedirect.jsp", type=
ServletDispatcherResult.class)
/jsp/tables/findAllTablesRedirect.jsp:
<% response.sendRedirect("/eventoos/tables/findAllTables.action?eid="+request.getParameter("eid")+"&etid="+request.getParameter("etid"));
%>
