rmacfi Two newbie questions: Attempt to de-reference a null object and Priority -flag on messaging
I'm trying to make a simple notification for non-SF users that is triggered by creation or updating of a case. The first problem I ran into was a null object error on the following code:
trigger newCaseToCustomerService on Case (after insert, after update) {
Case myCase = trigger.new[0];
Account myAccount = myCase.Account;
User myOwner = myCase.Owner;
String CRLF = '\r\n'
String msgbody;
if(myAccount.BillingCountry == 'Denmark'){
//code here
}
}when SF is inserting or updating the Case, why would the Account or Owner be null since they are set in the case properties? I noticed from the other messages asking help for the null object issues that a common approach was to use SOSQL query to access related objects but I don't quite get it why is that?
My second question is about the Messaging -class: Does the Apex Email Class allow setting the Priority -flag on outbound, single messages?

Are you sure Account.billing country is populated?
You might want to perform a null check on it before comparing it to a literal String.
Also, you might want to look into the API documentation as to whether or not the mail priority can be set
