Subject Re: portal tools i18n only work the first time in 2.1.7.
Date Wed, 25 May 2005 10:42:24 GMT
Hi

I had had a similar problem so I've changed the I18nCatalogueGenerator.java
My problem was that the generator was not able to serve the i18n
transformer with the right messages. E.g. if the user-language was
Arabic, then the generator delivered not the default messages.

I made a workaround which works for me:
