scottnelsonsmith apex:selectList; error "An error occurred when processing your submitted information."
I've reduced my code down to the minimum to get this result. What I'm trying to do is run a process against a subset of contacts for an account. Here's the VisualSource page and the controller code:
// The visualsource page:
<apex:page standardController="Account" tabStyle="Account" sidebar="false" extensions="AccountExtensions">
<apex:form >
<apex:pageBlock title="Assign Sector Access Logs">
<apex:messages />
<apex:pageBlockButtons >
<apex:commandButton action="{!save}" value="Mass Assign" id="massAssign" />
<apex:commandButton action="{!cancel}" value="Cancel" id="massCancel" />
</apex:pageBlockButtons>
<apex:pageBlockSection columns="1">
<apex:pageBlockSectionItem >
<apex:outputLabel value="Contacts to mass-assign SAL's to:" for="contacts_list"/>
<apex:selectList value="{!selContacts}" size="10" multiselect="true" id="contacts_list" required="true">
<apex:selectOptions value="{!contactsForAccount}" />
</apex:selectList>
</apex:pageBlockSectionItem>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>
// The controller
public with sharing class AccountExtensions
{
private final Account account;
private List<Contact> contacts;
private List<SelectOption> selContacts;
public AccountExtensions(Apexpages.StandardController asControl)
{
this.account = (Account) asControl.getRecord();
this.contacts = [select id, name, AccountId from Contact where AccountId = : account.id];
this.selContacts = new List<SelectOption>();
}
public PageReference save()
{
System.debug(' **** Begin save **** ');
return null;
}
public List<SelectOption> getSelContacts()
{
return this.selContacts;
}
public void setSelContacts( List<SelectOption> selected)
{
this.selContacts = selected;
}
public List<SelectOption> getContactsForAccount()
{
List<SelectOption> options = new List<SelectOption>();
for( Contact c : contacts)
{
options.add(new SelectOption(c.id, c.name));
}
return options;
}
public void setContactsForAccount(List<SelectOption> options)
{
}
}
When I click the "Mass Assign" button, I get the following "validation" message:
Ah, found the problem.
selContacts needs to be String[], not List<SelectOption>.
Better diagnostic message would definitely help.
New listing for those who are interested:
public with sharing class AccountExtensions { private final Account account; private List<Contact> contacts; private List<String> selectContacts; public AccountExtensions(Apexpages.StandardController asControl) { this.account = (Account) asControl.getRecord(); this.contacts = [select id, name, AccountId from Contact where AccountId = : account.id]; this.selectContacts = new List<String>(); } public PageReference save() { System.debug(' **** Begin save **** '); return null; } public List<String> selContacts { get { return this.selectContacts; } set { System.debug('*** Called? ***'); this.selectContacts = value; } } public List<SelectOption> getContactsForAccount() { List<SelectOption> options = new List<SelectOption>(); for( Contact c : contacts) { options.add(new SelectOption(c.id, c.name)); } return options; } public void setContactsForAccount(List<SelectOption> options) { } }
