How to prefill the title of a dexterity add form

[h2o]

There is an attribute (allow_prefill_from_GET_request) you can set to allow this. See full discussion on the thread below:

Security patch has been released: 20160830

Note that by default Plone 4.1.x, 4.2.x, and 4.3.x use a version of plone.app.discussion that has this problem. Some remarks: If you don't have comments enabled, you don't need to update. Previous versions of the hotfix may seem to work, because the comment is not shown on the page anymore. But when you reload the page, the comment is still there. If you have enabled comment moderation, then for new comments you can still bulk delete them on the moderation page.
