Select Options problem

I couldn't capture and display the options selected in the visualforce page. I include my controller and visualforce page. Intent is a custom object. Everything looks fine, don't know what i am missing.

 

 

public class intent{

String[] intent;

public String[] getintent(){
       return intent;
}

public void setintent(String[] intent){
        this.intent = intent;
}

public list<SelectOption> getintents(){

    list<Intent__c> custintents = new list<Intent__c>();
    custintents = [SELECT Name FROM Intent__c order by CreatedDate ASC];
    
    List<SelectOption> options = new List<SelectOption>();
    
    for(Intent__c custintent : custintents){
        options.add(new SelectOption(custintent.Name,custintent.Name));
    } 
    return options;
}

public PageReference Next(){ 
    return null;

}

}

 

<apex:page controller="intent">
<apex:form id="form1">
    <apex:selectCheckboxes value="{!intent}" onselect="{!intent}">
        <apex:selectOptions value="{!intents}"> </apex:selectOptions>
    </apex:selectCheckboxes>
    <apex:commandButton action="{!Next}" value="Next" reRender="out" status="status"/>
</apex:form> 

<apex:outputPanel id="out">
        <apex:actionstatus id="status" startText="testing...">
            <apex:facet name="stop">
                <apex:outputPanel >
                    <p>You have selected:</p>
                    <apex:dataList value="{!intent}" var="c">a:{!c}</apex:dataList>
                </apex:outputPanel>
            </apex:facet>
        </apex:actionstatus>
    </apex:outputPanel>
       
</apex:page>

Hi,

 

             You are not instantiated the array of strings thats why you are not able to display the selected values.

 

             Please replace with the following line.

 

             public String[] intent = new String[]{};

Thanks sivarajan. How silly of me to miss that part. I am going to mark your response as solution. I have a simple follow up question, when i change the tag from <apex:Checkboxes> to <apex:selectList>, its not working again. Bottom line is i should be able to select only one option thats why i wanted to use either selectList or selectRadio but its not working for both tags.

 

Thanks.

Hi Siva,

 

If you want to use Apex: selectRadio or SelectList then you should do the following changes in vf page and & Controller :

 

Controller :

 

Declare variable 'intent' as simple string (Remove the array). and also change the getter and setter method to remove the array.

 

Vf page :

 

Remove the data List and use Apex:outputText to print selected value.
