Comment puis-je obtenir les valeurs de liste sélectionnées dans Salesforce?

Question

Je passe ma page Visualforce le code suivant pour avoir aux utilisateurs de sélectionner un site d'emploi pour poster une position sur:

<apex:page standardController="Position__c" extensions="PositionExtension"> 
<apex:form > 
<apex:pageBlock title="Create New Position"> 
    <apex:pageBlockButtons > 

    <apex:commandButton title="Save" value="Save" action="{!save}"/> 
    <apex:commandButton title="Edit" value="Edit" action="{!edit}"/> 
    <apex:commandButton title="Cancel" value="Cancel" action="{!cancel}"/> 

    </apex:pageBlockButtons> 


<apex:pageBlockSection columns="3" title="Basic Information"> 

<apex:pageBlockSectionItem > 

    Position Title 
    <apex:inputField value="{!Position__c.name}" required="true"/> 
</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 
    Record Type 
    <apex:inputField value="{!Position__c.recordtypeId}" required="true"/> 
</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 
    Open Date 

    <apex:inputField value="{!Position__c.Open_Date__c}"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Close Date 

    <apex:inputField value="{!Position__c.Close_Date__c}"/> 

    </apex:pageBlockSectionItem> 

    <apex:pageBlockSectionItem > 

    Hire By 

    <apex:inputField value="{!Position__c.Hire_By__c}"/> 

</apex:pageBlockSectionItem> 


<apex:pageBlockSectionItem >  

    Job Type 
    <apex:inputField value="{!Position__c.Type__c}" required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Location 
    <apex:inputField value="{!Position__c.Location__c}" required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Travel Required? 

    <apex:inputField value="{!Position__c.Travel_Required__c}" required="false"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem >  

    Status 
    <apex:inputField value="{!Position__c.Status__c}" required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem >  

    Functional Area 
    <apex:inputField value="{!Position__c.Functional_Area__c}" required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem >  

    Job Level 
    <apex:inputField value="{!Position__c.Job_Level__c}" required="true"/> 

</apex:pageBlockSectionItem> 


<apex:pageBlockSectionItem > 

    Job Description 
    <apex:inputField value="{!Position__c.Job_Description__c}" required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Responsibilities 
    <apex:inputField value="{!Position__c.Responsibilities__c}" 
required="true"/> 

</apex:pageBlockSectionItem> 

<br></br> 

<apex:pageBlockSectionItem > 

    Min Pay 
    <apex:inputField value="{!Position__c.Min_Pay__c}" 
required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Max Pay 
    <apex:inputField value="{!Position__c.Max_Pay__c}" 
required="true"/> 

</apex:pageBlockSectionItem> 

</apex:pageBlockSection> 


<apex:pageBlockSection title="Education and Skills" columns="3"> 


<apex:pageBlockSectionItem > 

    Educational Requirements 
    <apex:inputField value="{!Position__c.Educational_Requirements__c}" 
required="true"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Skills Required   
    <apex:inputField value="{!Position__c.Skills_Required__c}" required="false"/> 

</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 

    Apex 
    <apex:inputField value="{!Position__c.Apex__c}"/> 
</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 
    C# 
    <apex:inputField value="{!Position__c.C_sharp__c}"/> 
</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 
    Java 
    <apex:inputField value="{!Position__c.Java__c}"/> 
</apex:pageBlockSectionItem> 

<apex:pageBlockSectionItem > 
    JavaScript 
    <apex:inputField value="{!Position__c.JavaScript__c}"/> 
</apex:pageBlockSectionItem> 

<apex:selectList value="{!selected}" multiselect="true"> 
    <apex:selectOptions value="{!websites}"/> 
</apex:selectList> 






</apex:pageBlockSection> 


</apex:pageBlock> 
</apex:Form> 
</apex:page> 

Et c'est le code du contrôleur, où je tente de récupérer les valeurs sélectionnées et trier pour déterminer si le site a été sélectionné:

public class PositionExtension { 

public Position__c pos{get; set;} 
public List<Employment_Website__c> employ{get;set;} 
Public List<Job_Posting__c> joblist = new List<Job_Posting__c>(); 
Public Set<String> selected{get;set;} 

public PositionExtension (ApexPages.StandardController controller){ 

    pos = (Position__c)Controller.getRecord(); 

} 

//List<Job_Posting__c> postings = [SELECT Id, Employment_Website__c FROM Job_Posting__c WHERE Position__c = :pos.Id]; 

public List<Employment_Website__c> website{ 

    get{return [SELECT Id, Name, web_address__c FROM Employment_Website__c];} 
    set{website = value;} 

} 

public List<SelectOption> getWebsites(){ 

    List<SelectOption> options = new List<SelectOption>(); 
    for (Employment_Website__c web : website){ 


     options.add(new SelectOption(web.Id, web.name)); 

    } 

    return options; 
} 

public Set<String> updateSelected(){ 

    return selected; 
} 

public PageReference save(){ 

    //List<Job_Posting__c> postings = [SELECT Id, Employment_Website__c FROM Job_Posting__c WHERE Position__c = :pos.Id]; 

    upsert pos; 

    for(Employment_Website__c web : website){ 
     system.debug(selected); 
     if(selected.contains(web.Id)){ 
      Job_Posting__c posting = new Job_Posting__c(); 
      posting.Employment_Website__c = web.Id; 
      posting.Position__c = pos.Id; 
      joblist.add(posting); 
     } 
    } 

    upsert joblist; 


    PageReference acctPage = new ApexPages.StandardController(pos).view(); 
    acctPage.setRedirect(true); 
    return acctPage; 

} 
} 

Toutes les suggestions sur la façon d'obtenir les valeurs sélectionnées dans le régulateur pour créer une offre d'emploi? Faites-moi savoir si je devrais poster plus de mon code Visualforce. Merci!

Answer 1

Vous devez convertir le type de données pour sélectionné.

actuel: Set public sélectionné {get; ensemble;}

Mise à jour publique Liste sélectionnée {get; set;}
