mod-db-add: How to use ManualAutoIncrementModule?

Hi -

is there an example on how to use the modular database actions (esp. 
mod-db-add) with 
manual autoincrement. I use mysql, but do not want to acivate autoincrement for 
the 
database column. How can I configure the database descriptor file to use 
   org.apache.cocoon.components.modules.database.ManualAutoIncrementModule
In cocoon.xconf all autoincrement modules are named "auto" and according to 
http://cocoon.apache.org/2.0/userdocs/concepts/modules.html
this should not be changed.
Could someone give me a hint based on the AutoIncrement sample included in the 
cocoon2.1 
distribution (requiring autoincrement activated for the table column in 
database):
<keys>
         <key name="uid" type="int" autoincerement="true">
           <mode name="auto" type="autoincr">
...

Thank you, regards - 
Christian

You can always specify the mode to use explicitly. 

Another way is to

       <map:action name="mod-db-add" src="org.apache.cocoon.acting.modular.DatabaseAddAction">
          <descriptor>database.xml</descriptor>
          <throw-exception>false</throw-exception>
          <autoincrement>auto</autoincrement>
       </map:action>

Specify the default mode for autoincrements. IIRC this currently
defaults to "manual" and not "auto" -> you could as well name the
manual autoincrement module to "manual" in cocoon.xconf and don't fuzz
with the default mode.

I'm not sure if the <mode..../> line above really works. I'm afraid
that there is a bug somewhere.... I will try to look into that but you
should be alright with the suggestions above.
