I just checked with the team and this is a known issue.

WHen using the JCR API - you can get props - as Marc as shown.

Just install the package where you backed up your data

As Arun has pointed out - you must use the Asset API to perform this use case.

Most of the custom logging requires you to map log to Java packages defined in code.

All that you want to do in Event Handler can be coded into a workflow.

We have no Doc for this use case that i can point you to.

See this - Internationalizing UI Strings

Are you seeing any error message - if everything is setup the same way - it will work.

You should not use the same name in a dialog (I assume that is what you mean).  As Ravi points out - you would have conflicts. Best practice for working with dialogs and Granite can be found here - Building Experience Manager Components using Granite/Coral Resource Types
