Task with Authenticated Website

Question

Can I run following code after login as customer portal user in apex controller?

task.WhatId = Object.id;
task.WhoId = Object.Editor__c;
task.Subject = 'Other';
task.priority= Object.Priority__c;
task.status = 'Not Started';
task.description = 'New  Work';
insert task;

I am getting error "Currently DML is not allowed". I want to create a task for customer portal user. Is that possible? I don't want show it to any user. I will just use it to send notification email. Is there any way to do so?

Answer 1

Well seems like you are doing DML from either Constructor or Getter method. Please try to do the same from action attribute of the page by calling a method

Answer 2

There's a blog post about this from Wes Nolte that even contains a short poem:

This covers all of the scenarios and solutions for each of them.
