Form bean population for and 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:

Are you hosting this as a project somewhere? Sourceforge?
If not, then might want to.
The Struts project on SourceForge is a great place for these kinds of
enhancements/extensions.
http://sourceforge.net/projects/struts
If you want, let me know and I'll add you. That would allow you to package
and release it with incremental improvements and also allow others to use and
modify the source to their liking (the essence of OSS).

A Question about Patches
Posted by DeRose Jonathan <de...@bah.com>.
I have a question about a patch I submitted,
http://issues.apache.org/bugzilla/show_bug.cgi?id=20784
A quick summary for anyone who may have missed it:
The enhancement provides lots of new functionality for error handling
beyond writing out the errors. (Developers could use it to highlight errored
inputs, create errors on a group of input elements, have their labels turn
bold and red, and lots more...
It is flexible and allows developers to set up these styles to whatever is
suitable for their application, or leave them out completely. It is
completely backwards compatible.</PLUG>
I have received several positive replies from people both on the list and
in private emails. I would like to know if there is anything I can do next.
I apologize as I am new to collaboration in an open source environment. I
do not want to push too hard, nor do I want to let this enhancement slip
through the cracks. So if there is anything I can do to promote this
enhancement/refine it/answer questions about it, I would love to do so. I
think it would be a really great addition to Struts.
Thanks for any help/insight,
Jonathan
