Subject: Form bean population for <logic:iterate> and
<nested:iterate>
tags
Hello folks,
I have the following problem using <nested:iterate> and
<logic:iterate> tags. Please help me some one.
Problem:
When i set the values for first time in my action class and
forward to jsp page i.e pre-populate , the values are set
and works well. But after prepopulating, when i change
values in the jsp page and try to submit the form, then i
get the "BeanUtils.populate" errors. Is it because, i am
trying to populate list/some other reason?
Here i have listed
1. struts code
2. Form Bean code
3. TraineeScoresListBean code
4. Errors
Any suggestions? Please help me, ASAP. Thank You.
1. Here is my form using struts:
a. Using logic:iterate
<logic:iterate id="element" name="perfTestGradeForm"
property="traineeScoresList" >
<html::text property="score" name="element" size="5"
maxlength="4" /><br />
</logic:iterate>
b. using nested:iterate
<nested:iterate name="perfTestGradeForm"
property="traineeScoresList" >
<nested:text property="score" size="5" maxlength="4" /><br
/>
</nested:iterate>
Here the list 'traineeScoresList' is collection of beans
'TraineeTaskScoreListBean' that has attribute 'score' of
datatype 'String'.
2. Form Bean Code:
public final class PerfTestGradeFormBean extends ActionForm
{
//this traineeScoresList will have TraineeTaskScoreListBean
that has
// score as an attribute
private Collection traineeScoresList = new Vector();
public PerfTestGradeForm(){
this.traineeScoresList = new Vector();
}
public Collection getTraineeScoresList(){
System.out.println("In perftestgradeform.java:
getTraineeScore...()");
return this.traineeScoresList;
}
public void setTraineeScoresList(Collection list){
this.traineeScoresList = list;
}
}
3. Here is Code for TraineeTaskScoreListBean:
public class TraineeTaskScoreListBean{
private String score;
public TraineeTaskScoreListBean(String score){
this.score = score;
}
public String getScore(){
return this.score;
}
public void setScore(String score){
this.score = score;
}
}
4. Errors:
