I am migrating to 3.1 rc 2 and I am seeing a similar problem.

We have subject and division ids that contain . and _ it looks like the . and _ are replaced with =2E and =5F respectively

The urls in the generated browse pages use =2E and =5F but the generated files use . and _

So the browse by subject page would have the link http://server.reading.ac.uk/view/subjects/I=2E4=2E8/ but the url that works is is http://server.reading.ac.uk/view/subjects/I.4.8/

similarly the browse by division page would have a link http://server.reading.ac.uk/view/divisions/dept=5Fmet/ but the url that works is http://server.reading.ac.uk/view/divisions/dept_met/

The urls by year inside the above pages are correct e.g.

http://server.reading.ac.uk/view/subjects/I.4.8/1996.html

http://server.reading.ac.uk/view/divisions/dept_met/2008.html

Any ideas what is causing this?

Hi Tim,

Thanks for the reply. I discovered that it was fixed in rc2 yesterday too! I am very happy about it. Congrats to the EPrints developers!

Hi Henok,

I think these problems are fixed in 3.1 rc 2. Certainly should be fixed by the 3.1 release.

Cheers,
Tim.

Okay, so I learned that there is a general issue with browsing by fields that have spaces in them. So if I want to browse by "funders" and the funder is University of Southampton, it throws an exception. I know some people have found a work around to this so please help if you know how?

Thanks

Hi all,

I put the following in views.pl
{
id => "people",
fields => "creators_name/editors_name",
order => "title",
},

and when running "generate_views repo_id" I get the following
error "Invalid path value 'last_name:first_name' in menu:
people/lastname:firstname ' for as many creators in database.

I would appreciate your help.

Thanks
