Warn users when a CCK field changes



Hello,

Imagine that I'd change the data type of a field in a content type (Ex: Number to checkbox) in CCK. Would it be possible to automatically inform my users about this change, so they can take the necesarry steps to update their content? (for example by changing the workflow-status of all content of this content type to a "to be reviewed" status.)

Is there a hook in CCK that is called upon changing the data type of a field?

Kind Regards,

mertens
