Hi, I had the same problem and i've solved by creating in my module, a new
class navEleSortNavText extending the CmsJspNavElement class and changing
the compareTo method used in the sort method of a Collection and adding the
contructor.
Then in another class I've cut and paste the src of three methods
getSiteNavigation getNavigationForFolder getNavigationForResource
and changed the name (added NavText ) and the code to create a list of the
new navEleSortNavText class.
So now when I call getNavigationForFolderNavText(...) I get the tree ordered
by NavText, if you change the compareTo method you can sort as you like.
Hope it helps.
Ciao.
Stefano.
Here the code of the new class e the three methods.

Oggetto: Re: [opencms-dev] Sort in Explorer View
Well, maybe that is what he is concerned about... And thusly he wants
to know about the order just by looking at the order of contents of the
folder. I've heard a similar request and ideally one should have the
option to switch between standard (alphabetically) and NavPos-based
ordering of the listing or maybe even some sort of generic
ordering-function applicable to all display columns. Maybe something
for 6.1...
Luckily, the workarounds are not that bad, i.e. click on a file in the
folder and look at the resulting page, or lock a file and use the
"change navigation" to inspect the ordering. Most users can come to
terms with either of these "hacks".
