Re: [VuFind-Tech] Browse problem: unreliable prev/next links

[Tod O. <to...@uc...>]

Yes, debug mode does show that. I don't see anything obviously wrong in either the JSON or XML representations: 

	http://magma.lib.uchicago.edu:8080/solr/biblio/browse?wt=json&json.nl=arrarr&from=p&offset=-20&rows=20&source=title
	http://magma.lib.uchicago.edu:8080/solr/biblio/browse?from=p&offset=-20&rows=20&source=title

So back to the PHP code, I guess. Well, first my next conference call, _then_ back to the PHP.

One thing that is interesting: the presence of the '<lst name="extras">'. That looks like the mechanism that Alan uses to return extra column data!
