You've specified 'selectKeyword' for every attribute... Each of those
attributes has a different meaning, so this wont work.
You need two properties on your action:
1) a collection of possible choices for the user to select from
2) a collection of values that have been selected
In the s:select tag, you need to set:
'name' (or 'key') to the property that will record what was selected
'list' to the property that contains all possible choices
If the property you specify in the 'list' attribute is a Map (as you
said in your first post) that's it. If it's not a map, you'll probably
need to also specify 'listKey' and 'listValue'.
Here's an example (not tested):
- action code:
public Map getAvailableKeywords() { ... }
public List getSelectedKeywords() { ... }
public void setSelectedKeywords(List selected) { ... }
- JSP code:
<s:select name="selectedKeywords list="availableKeywords"/>

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.

Hi,
I am trying to use the select tag and somehow it does not work as
expected.
I am populating a Map with the desired values and using that Map object in
the select tag.
<----- Start JSP ----->
<s:select value="selectKeyword" theme="simple" key="selectKeyword"
id="selectKeyword" name="selectKeyword" list="selectKeyword"
multiple="true"></s:select>
<----- End JSP ----->
<----- Start Action Code ----->
private Map selectKeyword = new HashMap();
public void setSelectKeyword(Map selectKeyword) {
log.debug(LoginAction.class.getName() + ": execute() : HERE
AFASDFSD");
this.selectKeyword = selectKeyword;
}
public Map getSelectKeyword() {
return selectKeyword;
}
public String execute()
{
selectKeyword = populateHashMap();
return SUCCESS;
}
/* This gets called when I submit the form */
public String saveKeyword()
{
System.out.println("This prints size as 0 : " +
selectKeyword.size());
}
<----- End Action Code ----->
I am able to view the populated list box but when I try to retrieve the
value back in my code, I am not getting any value.
Any idea where I am going wrong?
