Hi devs,
I currently get a NullPointerException on generating the Pojo and hbm.xml files on two certain tables. Sadly, the stacktrace of myEclipse did not reveal a lot.
I also made sure, that this is not due to my own templates, by deactivating the option.Here is the stacktrace I get from myEclipse .log:

Sorry that you are seeing this issue.
1. Can you please recheck your tables if a case where the foreign key column contains a value without a match in the pk column exists? Please ensure that there are no issues with foreign keys and their related tables.
2. The DDL which you have sent is not complete enough for us to investigate. Can you please put together a DDL for a set of tables that exhibit the problem to help us investigate further ?
