My problem is the input side rather than the output/display side. Consider ClassE (the embedded Object) containing more than one instance variable (which is a bit closer to my real world problem). Let's say ClassE has 2 instance variables like int classEVar1 String classEVar2 // <-- new The conversion from the ClassE object to Strings seems to be quite straightforward. I could pass the ClassE instance to 2 different converters, one to convert classEVar1 to a String and another one to convert (extract) classEVar2. Quite inconvenient since I need 2 converters, but that can be done. However, I don't know how to deal with the input fields since 2 different input fields are comprising a single ClassE instance. You know, if I follow the approach with the 2 different converters from above, they will produce 2 different ClassE objects, one containing classEVar1 and another one classEVar2. That won't work. Hence it looks like I need a converter which is able to handle multiple input Strings and produces a single ClassE Object. Is that possible at all?
