Okay, now database documents behave as other documents do (and as is required in
the DevGuide): Closing the document implicitly closes all associated views.
Also, closing the last view implicitly closes the document.
There's a few implications:
- Script developers who want to use a document need to ensure that it's not
closed
as long as they need it. That is, if a script doing potentially long-running
processings on a document need to add as CloseVetoListener. Else, it might be
possible that the user (while the script is running in the background) opens
the very same document, and closes the view, and thus the document - which
might
break the script.
- Script developers should definately close the document they use, even if they
did not obtain it from a loadComponentFromURL. This is especially important
for database documents, where there are more means to obtain the document
(e.g. DatabaseContext.getByName( "..." ).getDatabaseDocument)
- As a consequence of the previous item, the following scenario is possible:
- A script obtains a document, and does some processing with it (which at
least might involve reading some facets, not necessarily modifying it)
- The user opens the very same document and works with it
- The script finishs, closing the document
=> the user's views to the document are closed, too
The last is an immediate consequence from the fact that views to not veto
closing the document. However, it's by design (at least by what the DevGuide
requires :), and should be exotic enough to not hurt ....
