I am working with Apache Isis Wicket viewer 1.9.0, and I have some form layout json files to define the layout for some domain objects. I also added a translation file (i18n) with some translations. When running the application in the browser, when I am in “writing translations” mode it shows the object form with the layout defined in the json file (ok), but when I switch to “reading translations”, it goes back to the “default” layout, ignoring the layout defined in the json file.
In regards to those modes, I am referring to the Apache wicket viewer menu which, in prototype mode, has a "Prototyping" menu, which has an option "Switch to Reading Translations". When you select that option and keep using the application is when it loses the layouts defined in the json layout files.
