Dears,

As I know customer portal users can access activities,but I don't know whether they can create activities?

If it does, please tell me how to do it ,

Best guards.

/*

Purpose: When there is nobody in Account Team,Users can not create contact under the account.

*/

trigger Contact_CanNotCreatetheContact on Contact (before insert) {

    for(Contact con:Trigger.new){

        List atmList = [SELECT UserId FROM AccountTeamMember  WHERE AccountId =:con.AccountId];

        if(atmList == NULL){

            Contact conOld = Trigger.newMap.get(con.Id);

            conOld.addError('There is no Account Team Member,you can not create account children!');

        }

   }

}

Here is my code,When, I create the contact under account with no account team member,there is no error message and nothing happend,Finally,I just save the new record.

Could you help my find the problem?

      List<Account> accList = [select Id,Name,(select AccountId,Name from Contacts) from account where Id =                   :Trigger.newMap.keySet()];
// Map<Id,Contact> conMap = new Map<Id,Contact>([select Id from Contact where AccountId in: accList.Id]);
     List<Contact> conList = [select Name,isAccountChanged__c from Contact where AccountId in: accList];
     for(Account acc:accList){
