[opencms-dev] How to list files from a folder in opencms?

[mihai lacusteanu]

But is there a way to modify the content? I need to change a field from the
resource type any time another field gets modified.
I have 2 fields: *folder*, and *listOfFiles* and I need to update the
*listOfFiles* field any time the *folder* field gets modified.
I don't know how to do that in the formatter..or there is another place for
putting my code?(I guess that regenerating the *listOfFiles* any time the
page loads is not a good idea)
