I understand that in some case you don't want to empty view cache after each information collection but there should be a way to control this.

For now, it leads to a bug in eZ Flow/ eZ Webin -> the line view of a poll display a wrong the number of vote.

Can't you add a control on cache clear in eZContentObjectAttribute::collectInformation() ?

Steps to reproduce

• In a fresh install, create a folder that contains some poll.
• Go to the folder and you will see the line view of the polls dispaying the number of vote (0 for now).
• vote on a poll
• go back to the folder and the number of vote is not updated (view cache is still here !)
