Hello - I am getting the following error when attempting to Save a record using a VisualForce Page (VisualForcExtension) and a Controller Extension (positionExtension):
System.NullPointerException: Attempt to de-reference a null object
Class.positionExtension.Save: line 54, column 16 External entry point (line 54 column 16 is underlined in the following code fragment "return theController.save()")
The code from the positionExtension Apex Class:
public class positionExtension {
public string positionTypeID {get; set;}
public positionExtension(ApexPages.StandardController
positionController) {
this.position = (Position__c)positionController.getRecord();
}
public List<selectOption> PositionTypeOptions {get {
List<selectOption> positionTypes = new List<selectOption>();
for (Position_Type__c ptr :
[select name from Position_Type__c pt where pt.Department__c =
:position.Department__c order by Name ])
positionTypes.add(new selectOption(ptr.id, ptr.name));
if (position.Department__c != null) {
positionTypes.add(new selectOption('other', 'Other'));
}
else {
positionTypes.add(new selectOption('', 'Please select a department', true));
}

I've created a small Java Aplication which can do an login in salesforce and which proviedes a list with all accounts. My question is how i can start this from salesforce? For example i have a button on the start page and if i touch it, my Java-Program should start.
If you look at the Apex Language reference pdf, on page 278, you will see an example of how to invoke an action from within another action. This sounds great in theory but doesn't work in practice. All we get is a system error like this:
Salesforce System Error: 1598249974-2475 (-814351657) (-814351657)
An unexpected error has occurred. Your solution provider has been notified. (ApexPages)
To save you time, here is the code:
Controller:
public with sharing class Page2Controller {
private ApexPages.Action saveAction = new ApexPages.Action('{!onSave}');
public Page2Controller() {
}
public PageReference doSomething() {
saveAction.invoke();
return null;
}
public void onSave() {
ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.Error, 'why dont I work?'));
}
}
I have a custom button on a contact list view that's connected to a VF page. All I want to do on the VF page is run some DML to update the selected contacts, then go back to the list view, as long as at least one contact was selected. If no contacts were selected, I want to display an err message. When I run the page, whether or not I've selected any contacts, I get this err message: "Unknown method 'ContactBarcodeCreated.updateBarcodeCreated()'" Thanks for any help you can provide.
VF page tag:
Apex: public class ContactBarcodeCreated { public sObject[] objs { get; private set; } public boolean hasSelection { get; private set; }
public pageReference updateBarcodeCreated(ApexPages.StandardSetController controller ){ objs = controller.getSelected(); hasSelection = !objs.isEmpty(); if (hasSelection) {
Contact[] cons = new contact[0]; for (sObject c : objs){ cons.add(new Contact( id=c.id, Barcode_Card_Created__c = true, Barcode_Card_Created_Date__c = system.today() )); } update cons;
// go back string url = ApexPages.currentPage().getParameters().get('retURL'); pageReference prevPage = new PageReference((url != null) ? url : '/006'); prevPage.setRedirect(true); return prevPage; } else { return null; }

With some suggestions from SimonF on this board i was able to succesfully send a login() request and get a valid response. That was on the production server. Now I'm trying to do the same request to my sandbox and am getting a 'invalid login'.
The only changes i made were the endpoint and the username (added .sandboxname).
response:
<soapenv:Fault> <faultcode>sf:INVALID_LOGIN</faultcode> <faultstring>INVALID_LOGIN: Invalid username, password, security token; or user locked out.</faultstring> <detail> <sf:LoginFault xsi:type="sf:LoginFault"> <sf:exceptionCode>INVALID_LOGIN</sf:exceptionCode> <sf:exceptionMessage>Invalid username, password, security token; or user locked out.</sf:exceptionMessage> </sf:LoginFault> </detail> </soapenv:Fault>
I'm new to VF, coming from scontrols. I have some custom objects related to Opportunities which can each have tasks related to them. The salesguys want to see one list of tasks, no matter which of the custom objects or indeed the Opportunity itself they are related to. I've been trying to write a list controller for tasks with no luck at all. I know there is no standard controller for listing tasks but is there any reason why a custom controller would not work? Does anyone have some template code I could use as I'm new to Apex as well and I can't get my code accepted by the IDE?
Apex Code is as follows (still needs the query to be filtered but am trying to get proof of concept first):
public class OppTasks {
public ApexPages.StandardSetController setCon {
get {
if(setCon == null) {
setCon = new ApexPages.StandardSetController(Database.getQueryLocator([Select WhatId, Subject, Status, OwnerId, Id, Description, ActivityDate From Task]));
}
return setCon;
}
set;
}
public List<Task> getActivities() {
return (List<Task>) setCon.getRecords();
}
}
I am trying to connect to gmail imap servers using emailtocase.
The setup goes OK but I am getting an error which looks like the
process is refused connection to the gmail server. I have had the
config files checked by salesforce.com tech support and they said they
were OK.
Has anyone tried this process, or a similar one before? Does it work?
Has anyone any ideas why I might not be able to connect.
Here is a clip from the error log I get when running the process.

Currently we are working on uploading Opportunities data to SalesForce.com.
We completed our development and it was working very much fine before. But now when we tried uploading the same we are getting strange error (negative response) from salesforce as "Client Missing entity type information. sObject requires a separate 'type' field be sent.".
Really i did not understand whats the problem is? Could any one help me out in solving this problem?
