Hey Vilmos,


this is the localization export/import fix I was working on but was not able to finish. The problems I have is the some of the test (http://ci.liferay.org.es/jenkins/job/matethurzo/112/testReport/) fails on the Jenkis but works on the local environment. It is weird but still makes sense after looking at the code we have in model_impl.ftl prepareLocalizedFieldsForImport(Locale defaultImportLocale) method wehere we completely do not use the only parameter and it could lead the result the localized filed value map won't have any value for the site default locale (all the exceptions shows this result). 

thanks for the help,
Daniel
