[seam-dev] To cascade or not...

[Emmanuel Bernard]

Then add @*to*(cascade=CascadeType.PERSIST), it will take you 2 mins  
to do what you really like and you will know you do it.

Or even faster, add the stupid
<entity-mappings>
   <persistence-unit-metadata>
     <persistence-unit-defaults>
       <cascade-persist/>
     </persistence-unit-defaults>
   </persistence-unit-metadata>
</entity-mappings>
in your orm.xml file and you are good to go.

I really like smoking Chicha when drinking tea. Not sure it should be  
enforced to everyone. Not sure if I should do it every time either.
