Nesting Transactions

Hi all,

I wonder if anyone has tried nesting transactions with prevayler before.

To be specific, lets imagine two calls to the same transaction done  
sequentially.

LocalList.add( prevayler.execute ( new GetNutsTransaction( "Walnuts") ;
LocalList.add( prevayler.execute ( new GetNutsTransaction ("Pecans") ;

What I would like to do is make those two calls within the same  
transaction without being forced to code a sort of composite  
transaction.   Of course, what I am really getting at is the ability  
to arbitrarily start a transaction and then have that bundle all of  
the smaller transactions until I explicitly commit.   As a more  
realistic example, I would want to do something like this :

public void increaseNutPurchases(String[] nutTypes, int pctIncrease) {

     Transaction txn = startLongishTransaction();

     try {
         for (String nutType : nutTypes) {

             List growers = prevayler.execute(new  
GetGrowerQuery(nutType));
             for (Grower grower : growers) {

                 prevayler.execute(new  
UpdateBuyQuantityTransaction(grower, pctIncrease));

             }
         }
     }

     catch (Exception e) {
         txn.rollback();
     }
     txn.commit():

}


Has anyone tried this ??   Known issues?   Any red flags pop up for  
you looking at this?

Thx,

Rick
