Problems compiling internationalisation files with GWT 2.0

[craige]

Hi

I've just tried out GWT 2.0 on a mature GWT project after upgrading
from 1.6 and I'm noticing a compiler error relating to processing of
the internationalisation aspect of the application which I I have
never see before. I was wondering if this is a bug or that I possibly
need to change something in my project.

I'm using properties files for the internationalisation. The
properties files are called :

InternationalizationConstants_en.properties
InternationalizationConstants_es_GTC.properties
InternationalizationConstants_es.properties
InternationalizationConstants.java
InternationalizationConstants.properties

Reading between the lines, there seems to be some conflict between the
processing of the InternationalizationConstants_es_GTC.properties and
the InternationalizationConstants_es.properties files. In the compiler
output (see below) it complains about a compiler generated java file
(see below) which has been created.

If anybody has any ideas they would be most appreciated.

Many thanks

Craige

}

@Override

}

@Override

}




The compiler output is as follows :

Since upgrading to 2.0, I can no longe compile my i18n files as well.
The compiler complains for a missing key, although the interface/
properties files have not been altered and have worked under 1.5/1.6
and the latest 1.7.1 version. I basically cannot compile my app with
2.0.

Here is the error from the compiler:

Changing the name of my interface and the properties files resolved at
least my issue. No clue what was wrong with the old one... It simply
disliked it.
