Just thinking off the top of my head: Maybe post an NSNotification in the EO's willUpdate (assuming you are using subclasses of ERXGenericRecord) method if the textblock is changing. The notification should contain the EOGlobalID of the changed object.
Register to receive that kind of notification in your Session object, or somewhere else that it is appropriate to handle it. If the pdf generation takes time, consider trying something like ERXAsyncQueue to handle in the background.
