Subject RE: Struts 2 <s:select> tag : Unable to retrieve the value in theaction
Date Tue, 29 Apr 2008 03:36:24 GMT
This does not help. :(
I tried using the setter method as below

        void setSelectKeyword(String[] selectKeyword) {
        log.debug(LoginAction.class.getName() + ": execute() : Checkpoint 1");
        this.temp = selectKeyword;
    }

But the log statement even does not gets printed. That means that the setter is not even getting
called.
Also in the code fragment that you suggested, you specified that "selectedKeyword is what
is selected". How do we configure that?
Do we have to set some parameter to make sure that the values in the list are getting written
back using the setter?

1. Make sure all the options you want are selected. (e.g. if your selectKeyword list contains
all the entry that you want to be selected then make sure they are all highlighted when you
submit the form <maybe via a javascript>).
2. Try getting it back as an Array of something instead.

i.e. (assuming 1. doesn't apply. I have selectKeyword as the source to select from and selectedKeyword
which is what is selected)
private String[] selectedKeyword;
public void setSelectedKeyword(String[] selectedKeyword) {
         log.debug(LoginAction.class.getName() + ": execute() : HERE
 AFASDFSD");
         this.selectedKeyword = selectedKeyword;
 }

public String saveKeyword()
{
         System.out.println("selectedKeywords:" +
 selectedKeyword);
 }

Hope that helps.
