Bengt Rodehav commented on CAMEL-6335:
--------------------------------------

Point well taken - if you are allowed to go down stepwise you are most likely 
allowed to go back up stepwise. I guess you want to go back up stepwise for the 
same reason you want to go down stepwise. I just have never understood what 
situations the stepwise functionality actually remedies. What ftp server does 
not allow you to change directory directly ("CD subdirA/subdirB") but requires 
you to stop att every intermediate directory ("CD subdirA" then "CD subdirB")? 
What does actually happen?

I'm not opposed to the stepwise functionality but I have never found a 
situation where I have needed it and I'm just curious abou this since stepwise 
has been chosen as the default option for Camel.

Anyway, I guess all that is needed is to fix the code according to your 
suggestion. Then we'll have the best of both worlds (stepwise and not).

> The problem occurs when using the sftp protocol with the stepwise option 
> enabled and when polling a subdirectory.
> When Camel has finished polling the subdirectory, it attempts to change 
> directory back to the home directory in a stepwise fashion: Doing "cd .." one 
> step at a time. This logic has a bug that causes it to try to change to a 
> non-existing directory.
> This has been discussed on the user mailing list:
