Hi,
i' am using ER-Master 1.0.0.v20100429-1112. When i try to export my Database model to a png Image, i get an error message. Cause: illegal argument exception: formatName == null!. Export to HTML is also broken, only exporting to jpeg works well.
Besides: ERMaster is a very usefull plugin and png export worked for me in earlier versions.
Best Regards
