it seems that DDL-Utils does not manage data for views (i.e. does not export data, as import
for views won't mean much), and exports the schema with views.

In order to be able to read data from views, you probably have to
specify "TABLE, VIEW" for the tabletypes parameter
If that doesn't work, then could you please use the dumpMetadata task
on this database (schema) and send me the file so that I can see what
table types the database reports for the views ?

or am I doing something wrong ?

If they are in the schema XML, then this should work (though DdlUtils
will create normal tables, not views).
