Apex newbie quest continues.
When new Chatter comment is added to Case, custom field on Case should be populated with information from latest Chatter comment.
Currently I have developed a 'before update' trigger on Case. It works quite well and suits my requirements, however works only when a Case is updated (doh). Now I want to make this solution a bit more "good-looking" and create "after insert" trigger on FeedItem object.
So far I have managed to identify that FeedItem is related to Case using parentId field (using code mentioned here as a sample - http://www.salesforcefast.com/2012/02/get-object-name-from-record-id.html).
However, I don`t know how to update information on Case from FeedItem trigger knowing only Case id (which is FeedItem parentId). Can anyone point me to the right direction? Thanks.
