Put two independent entities in environment

I have this code generator that uses hibernate tools.

I’m trying to generate a DAO for a given entity mapped from a database table. I would like to check if there is another table with the same name + a suffix and, in that case, have availble in the environment, at the time of using the freemarker template, a second entity mapped from this second table.

I’ve tried to write a CustomGenericExporter with an exportPOJO method that puts the second POJO in the ‘additionalContext’ Map with no success.

If someone has a hint on how to approach this case I will really appreciate it. I can provide more info if necessary.

Thank you!
