[rules-users] Drools Decision Table, multiple actions accumulation

[Vincent LEGENDRE]

>> ... which would mean I should be able to pass the value present in both the columns in one method call.

Or create a Pojo for your keys (you should have already one as java maps only have one key ...),
instanciate it in the first column in a local (to RHS) variable, 
use setters to set internal keys,
then use this KeyPojo to add your value in the last column.

In DRL  this could be :
...
then
   KeyPojo keys = new KeyPojo();
   keys.setKey1(...);
   ...
   keys.setKeyk(...);
   ...
   keys.setKeyN(...);
   $myMap.put(keys, value);
end

basically, the fist action column will contains the 2 first DRL statements. 
The last action column will contains the 2 last DRL statement.
Intermediate columns only use the setters.

Of course, this works only if you are sure that your first and last action columns are always set ...
Otherwise, hope this help !
