During Tridion Developer Summit 2017 in Amsterdam (11-12 May), Trivident’s Siawash Shibani delivered a lightning talk about G4TM: GUI for Topology Manager. G4TM is the first alternative UI for SDL Web’s Topology Manager.
SDL Web 8 has been around for a little over a year now. Its successor (SDL Web 8.5) was recently introduced. You’d think that to an old Tridion hand like me, by now Web 8.x would be as familiar as any of the earlier (Tridion) versions. The sobering fact is that today I ran into an issue caused by a poor understanding on my side of SDL’s new microservices architecture. Fortunately it proved easy to fix.
Plato (~423 BC – ~347 BC) was a pretty smart guy. Among his many ideas and thoughts, his Theory of Forms had an immense influence on how we perceive and solve the philosophical Problem of universals. It basically comes down to the idea that every physical object has one or more essences (or Forms) and that if that object would not have that Form, it would not be that object: a dog is Mammal, but a giraffe is also a Mammal. What makes both animals Mammals? It’s, simply put, the Idea of the Mammal.
In part II of these series on ViewModel functionality in dd4t–2-java, it was explained how to create ViewModel classes and how to implement basic field types for the mapping between Tridion fields and DD4T ViewModel properties.
This post handles the more complex field types. The reason we make a distinction between ‘simple’ and ‘complex’ is mainly because the complex field types have more options to be deserialized into and need quite some help from DD4T to know what they will become.
