Trigger to help Salesforce for Twitter

October 6, 2009 by David Schach Leave a Comment

Salesforce for Twitter is one of the best AppExchange packages I've seen. It fulfills the promise salesforce.com made to bring the Service Cloud to all orgs of all sizes. And it works well. Though a supplemental/unofficial guide to customizing SFDC for Twitter will be released soon on this site, I wanted to share a trigger I just wrote to add new Leads to a campaign:

Filtered Lookups, Validation Rules, and Order of Execution

October 6, 2009 by David Schach Leave a Comment

Reading the cheatsheet for Filtered Lookup (beta), I noticed an interesting line:

Lookup filters function similarly to validation rules when you save a record. That is, actions that cause related records to save, such as changes to a roll-up summary fields, also trigger the lookup filters on the related record and block the save.

This will allow the app to support custom address fields and international address formats. I didn't want to write one ControllerExtension for the main page, a CustomController for the view section component, and another CustomController for the pageblocktable component. So here is the overloaded class constructor. Note that this works because an extension passes the StandardController to the constructor, and a CustomController passes nothing:

Pulling Code Out of Triggers

To date, triggers have only been accessible on each object's setup page, leading to a lot of hunting for code within the Salesforce CRM application.
