问题:

I have four select option list two are populated with data form the database and two are multi selects which are bind to the POJO. I then use java script to add options form the database select option list into the bind select option list however when i submit to the controller if the form is returned with errors and the select option list have data in it the data is lost.

The list items are both getting data properly only when the form is posted to the controller if the validation finds any errors and returns the form if these fields had data its lost.

I may have to write a CustomCollectionEditor for the list items in the class how can this be done?

Crime.java

public class Crime {

    private int crimeRecNo;
    private String crimeDetails;
    private double crimeLatLocation;
    private double crimeLongLocation;
    private String crimeStreetLn1;
    private String crimeStreetLn2;
    private Date crimeDate;
    private String crimeTime;
    private List<Citizens> victims;
    private List<Citizens> criminals;   
    private String recordedById;

//setters and getters

jsp:

<ol>
<li><label>Victims List</label><button id="addVictimBtn">+/button>

<form:select path="" id="dbvictims" title="Victims Of Crime" class="victimLst">
<form:options items="${dbvictims.dbvictimList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select>                      

<label>Victims In Crime</label><button id="removeVictimBtn">-</button> 
<form:select path="victims" id="victims" title="Victims Of Crime"  multiple="multiple" class="victimLst">
<form:options items="${victims.victimList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select><form:errors path="victims" class="errors" />                            
</li>
</ol>                           

<ol>
<li>
<label>Criminals List</label><button id="addCriminalBtn">+</button>
<form:select path="" id="dbcriminals" title="Criminals Of Crime" class="criminalsLst">
<form:options items="${dbcriminals.dbcriminalList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select>  

<label>Criminals In Crime</label><button id="removeCriminalBtn">-</button> 
<form:select path="criminals" id="criminals" title="Criminals Of Crime"  multiple="multiple" class="criminalsLst">
<form:options items="${criminals.criminalList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select><form:errors path="criminals" class="errors" />                           
</li>
</ol>

Jquery This is used to add items from the dblist to the from bind list elements

    $('#addVictimBtn').click(function(event){
        event.preventDefault();
        var victimId = $('#dbvictims option:selected').val();
        var victimName = $('#dbvictims option:selected').text();
        var options = '<option value="'+ victimId +'">' + victimName +'</option>';
        var exists = false;

    $('#victims option').each(function(){
        //alert($(this).val());
        if(this.value == victimId){

            exists = true;
        }                               
    });         

    if(!exists){
        $('#victims').append(options);              
    }           
    return false;           
});


$('#addCriminalBtn').click(function(event){
    event.preventDefault();
    var criminalId = $('#dbcriminals option:selected').val();
    var criminalName = $('#dbcriminals option:selected').text();
    var options = '<option value="'+ criminalId +'">' + criminalName +'</option>';
    var exists = false;

    $('#criminals option').each(function(){
        //alert($(this).val());
        if(this.value == criminalId){

            exists = true;
        }                               
    });         

    if(!exists){
        $('#criminals').append(options);            
    }           
    return false;           
});

Validation 

try{
   if(crime.getCriminals().isEmpty()){
    errors.rejectValue("criminals", "criminals.required");
   }                    

}catch(Exception e){
     errors.rejectValue("criminals", "criminals.required");
}


try{
   if(crime.getVictims().isEmpty()){
    errors.rejectValue("victims", "victims.required");
   }
}catch(Exception e){
    errors.rejectValue("victims", "victims.required");
}

Error

In the multi list if i select the options and then post the form i am getting the following error message

Failed to convert property value of type java.lang.String[] to required type java.util.List for property victims; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.crimetrack.business.Citizens] for property victims[0]: no matching editors or conversion strategy found Invalid List Of Victims
