I saved a file named types.skipper.cfg.xml
next to my project file BX Formation.skipper
and wrote the following content in it:
<?xml version="1.0"?>
<skipper-configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<mvc-support-orm mvc-name="Symfony2" orm-name="Doctrine2">
<data-types>
<data-type name="action_type"/>
</data-types>
</mvc-support-orm>
</skipper-configuration>
I expect to see the new "action_type" in the appropriate select box, but nothing new appear.
The procedure I did follow is explained here: Project configuration files
