trigger prevent_duplicate_account on Account (before insert) {
    map<id,Account> mapAcc = new map<id,Account>([Select id,name,rating from Account ]);
    for(Account a : Trigger.new)
    {
        if(a.Name==mapAcc.get(a.id).name && a.rating==mapAcc.get(a.id).rating)

Hi, 

I add a new formula field Complete_Date__c in a custom object named TDR, and want it shown in a VF page: 
<apex:outputField value="{!tdr.Complete_Date__c}" />
And I have added its readonly access to proper profile and permission set. 
But it is still blank in VF page. 
Anybody saw a similar issue before? thanks.

Tan Wenlong

Hello all,

 

I'm trying to create a lead using the Force.com REST API and able to do so successfully.

 

Now, I go ahead and delete that lead from Salesforce. 

 

If I try to create the same lead again via API, then it gives the following error:

[{"fields":[],"message":"entity is deleted","errorCode":"ENTITY_IS_DELETED"}]

 

I also tried deleting the lead from Recycle Bin in Salesforce, but that didn't helped.

 

Please let me know what I'm doing wrong.
