The current API only allows to inform the user
when the target chooser panel is going away. It is
a solution, but some actions which are already
done are irreversible, like creation of
nonexistent folders. (from issue 15267, parts 1st,
Postpone creating irreversible object (e.g.
harddrive, remote server) at the time when user
gone over wizard (i.e. Finish option).
I decrease the priority. There was only one known use-case (creating
new folders in TemplateWizard) where this task made a sense. Because
TemplateWizard has been broadly changed and an user has no use for
creating new folders, then this task is no urgent, needn't be fixed.
To be consistent with the last comment, I close as wontfix.
This issue was solved long time ago. Because nobody has reopened it neither
added comments, we are verifying/closing it now.
If you are still able to reproduce the problem, please reopen.
Thanks in advance.
