Side to side entity relationship diagram

Question

I want to create a kind of database diagram and I use the entity relationship arrow tips to show the relationship between fields, but I only can use it up to down, but not side by side.

Up to Down (This works but seems weird): http://www.plantuml.com/plantuml/umla/dStFIWCn4CVn-pp53tffaOgx9mbjgIxq1VG5nireG_Cd95cXTFlk1kjXtPCuno_yvhFFXLCPdAMZqO9S94aevoYPyiduo8dTf7QR3Gg_MS5kXmi1pzoVFb8OlEw23GcBm-6f7bsdynXAT-GqtRuIzPPpXXwSEsF-zeLTj79hzmHijmGiO3ICBylcOKN0kn6hctbeyScfhzgoQHzNTFtbjF-2xlvCVIDArVKuhjVZvKTLwlQ0zk9hiLy0

Some observations.

It's the source arrowhead it doesn't like, your ||-|{ causes an abend, and so does just ||- but -|{ renders fine.

 Adding an edge label (eg ": *")  stops the abend, but the render is very broken.  I.e. Using dummy::id ||-|{ dummy2::field1 : *

I thought 'skinparam linetype ortho' might fix it - it did fix attaching the arrowheads, but failed miserably in the placement of the two ends.  I've documented it here in case it's a different but related bug for @plantuml to consider:

Ok, Could you send the code for the image you just show up?

What can I do to use that arrow tips?, because I think that arrow tips are the one that are used in Database Diagrams.

I've added the code for my buggy pic above.  But I haven't got an answer for you, the class field to field linking isn't a documented feature (it has been around a while though, here's the earliest reference I found for it: https://forum.plantuml.net/5261) and seems to have bugs.
