tks very much, it works after change var to id.
Also, have further question need to bother you similar to it
same bean class
public class Bed {
private String bed_id;
public String getBed_id() {return bed_id;}
public void setBed_id(String bed_id) { this.bed_id=bed_id; }
}
same action class
...
private ArrayList<Bed> beds;
public String execute() throws Exception {
....
beds=service.Beds();
return SUCCESS;
}
public void setBeds(ArrayList<Bed> beds){ this.beds = beds; }
public ArrayList<Bed> getBeds() { return beds; }
almost same jsp file
<s:iterator value="beds" status="st" >
<s:property value="bed_id"/>
</s:iterator>
<s:select label="Bed ID" name="bed_id" headerKey="1" headerValue="Please
Select Bed#" list="beds"/> /* the problem */
the output is
1 2 3 4
...@188d92e
...@16a5bcb
b...@1b08cf3
....@1f5d699
my question is that why "s:select list" print object but value, is because i
defined ArrayList<Bed> ?
what is the correct way to fetch value out as <s:iterator><s:property
value="bed_id"/> did
tks in advance again
