    public PartnerLeadController(ApexPages.StandardController stdController) {
        LeadList = new List<Lead>();
        this.acc = (Account)stdController.getRecord();
        list<contact> conlist=[Select Id From Contact WHERE AccountId =:acc.Id]; 
        for(User u: [Select Id, Name, ContactId FROM USER WHERE isactive=TRUE AND ContactId In:conlist]){
            UserContactId.add(u.Id);
