I can't get custom orm attributes working for Propel.
I have the following custom orm2.cfg:
<?xml version="1.0" encoding="utf-8" standalone="no" ?>
<ormd2-configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<orm-configuration name="Propel" caption="Propel ORM" image="logoPropel.png" >
<attribute-types>
<struct name="Inheritance" section="orm" help-url="">
<attribute name="copy_data_to_child" type="string" />
</struct>
</attribute-types>
</orm-configuration>
</ormd2-configuration>
This creates the correct custom attribute on the inheritance, but it won't be saved and nor exported to the generated .xml file for Propel.
