Lee.ax1423 System.ListException: Before Insert or Upsert list must not have two identically equal elements
Hi, I am doing bulk insert in custom object from visualforce page using controllers.. In that custom object I have two fields called startdate__c ,enddate__c. I fired some validation rule on that i.e enddate__c < startdate__c. while I am entering data from visualforce page if I enter endate less than start date its showing error in visualforce page.. and after I correct and click save button it is showing System.ListException: Before Insert or Upsert list must not have two identically equal elements error. I am not aware of that.. can any one knows about this.. Here is my Controller :- public class ProjectMileStonesCon { /* public List wrappers {get; set;} public static Integer toDelIdent {get; set;} public static Integer addCount {get; set;} private Integer nextIdent=1; public Customobj1__c cusob; public List mls = new List(); public ProjectMileStonesCon(ApexPages.StandardController controller) { wrappers=new List(); cusob = (Customobj1__c)controller.getRecord(); for (Integer idx=1; idx<=1; idx++) { wrappers.add(new PTeamWrapper(nextIdent++,cusob)); } } public void delWrapper() { Integer toDelPos=-1; for (Integer idx=0; idx
Usually this happens when you're trying to put the same records into lists. Code inside the post is difficult to interpret, but i
guess you're adding records to the list in controller or method and click of it again in another method you're trying add the same
record to the list.
