Was anyone successful in getting their after insert trigger on Attachment working? I don't see any debug logs for the trigger when I try to invoke from the UI

Updating post to add my code:

trigger AttachmentTrigger on Attachment (after insert) {
   Map<id,List<Attachment>> taskAttachmentMap = new Map<id,List<Attachment>>();
    for(Attachment attachment: [SELECT Body,BodyLength,ContentType,Description,Id,IsPrivate,Name,ParentId FROM Attachment where Id IN :Trigger.new]){           
        String text= String.valueof(attachment.ParentId);
            List<Attachment> la = new List<Attachment>();
                la = taskAttachmentMap.get(attachment.parentId);
            taskAttachmentMap.put(attachment.parentId, la);                     


    List<Attachment> attachmentsToInsertonOpp = new List<Attachment>();
    //Find all tasks that are associated to opportunities
        for(Task t: [select id, whatid from Task where id IN :taskAttachmentMap.keyset()]){
                String text1 = String.valueof(t.whatid);
                    for(Attachment att:taskAttachmentMap.get(t.id) ){


    //Now insert attachments
        insert attachmentsToInsertonOpp;

  • What are you trying to do in the after insert event ? What actually do you see in the debug logs ? – Jarvis Feb 8 '16 at 21:17

Salesforce provides an example of an after insert trigger in the following link http://help.salesforce.com/HTViewSolution?id=000181538 . Here is the answer they provide.

A trigger can be written on Attachment using Force.com IDE or ANT.

A sample code would be:

trigger SetTitleToAttachment on Attachment (after insert) {

String Title;
Id pId;

for(Attachment att: Trigger.new){

List<Case> c=[select Id , Title__c from Case where Id=:pId];

//assuming one record is fetched.

update c[0];


Note: There is no way to write a trigger using the Salesforce.com UI (Portal).
