Hi!
When using these translations found in https://github.com/jmix-framework/jmix/blob/master/jmix-translations/content/io/jmix/datatoolsflowui/ there is a typographical error in the Keys expected by the framework and the ones found in these messages files, for the Data Model tool. Right now they are different than what the framework is expecting. To reproduce the problem, the jmix-translations/content/io folders should be copied to the resources folder of the project.
Some examples of Wrong keys:
io.jmix.datatoolsflowui.view.datadiagram/dataDiagramView.title=Data model diagram
io.jmix.datatoolsflowui.view.datamodel/dataModelListView.title=Data model
io.jmix.datatoolsflowui.view.datamodel/dataModelListView.searchButton.text=Search
io.jmix.datatoolsflowui.view.datamodel/entityModelListView.showSystemEntities.text=Show system
io.jmix.datatoolsflowui.view.datamodel/dataModelListView.diagramButton.text=Diagram
io.jmix.datatoolsflowui.view.datamodel/dataModelListView.entityModelsDataGrid.title=Entities
io.jmix.datatoolsflowui.view.datamodel/dataModelListView.attributeModelsDataGrid.title=Attributes
io.jmix.datatoolsflowui.view.datamodel/entityModelListView.entityFilter.placeholder.text=Search by entity names: User, Product, …
etc…
I am attaching an image. and a Test project.
