>From this we can conclude that the value is not found. OK, the issue
is a bit complicated here. And you coudn't have known unless
inspecting the source (which I did just now):

If you happen to insert a key column like Guiseppe did, you can use
   <key param="key:base:id" dbcol="id" type="int" mode="request-attribute"/>
Where the important part is the mode attribute.

If you want to insert into a "value" column, however, this is not
supported. Instead, you need to provide the complete request attribute
name which is prefixed with "org.apache.cocoon.acting.AbstractDatabaseAction:" 
thus it would be in your case 
org.apache.cocoon.acting.AbstractDatabaseAction:key:page:pageid

The action will first try to find a request parameter with that name
and then try a request attribute of that name.
