Get next entry from an entries field I am having the following sections:

1. work (section type: single)
  fields: 
    - workList (type: entries from section type workArticles)

2. workArticles (section type: channel)
  fields: 
    - workName (type: plain text)


So the first section (work) is an overview page that links to pages of the second section (workArticles). Basically a normal portfolio page.

On my workArticles pages I want to link to the next entry from work.workList. So imagine: my portfolio overview page shows 8 projects, the user clicks on the third entry, the page for the third entry opens, on the bottom of that page I want to link to the fourth entry of the list.

Is that even possible?
There is no inherent order or hierarchy between entries in a Channel section.  You could do some janky things to simulate it, but you're probably much better off converting that workArticles section to a Structured section, which does give its entries both order and hierarchy.

In your case, you might not care about the hierarchy, so you can just keep everything on the first level.

Very similar to https://craftcms.com/support/structure-nav#top-level-only

Then, if you need to, you can take advantage of all of the structure specific properties of EntryModel, (level, parent, nextSibling, etc.)
