[drools-user] Application-Data Problem

[Caroline . Grima]

Hi,
        Sorry to ask a question thats been asked before but I couldn't 
find a satisfactory reply. Is it possible to use application-data in the 
following manner:

 <application-data identifier="t">Transaction</application-data>


<rule name="rule1">
 
     ...............

     <java:consequence>
            t.setActionName("red");
 
     </java:consequence>
  </rule>


and then from my program do workingMemory.getApplicationData("t"); 

Right now I am receiving a Null Pointer exception in the consequence 
block. This is solved by doing 

<java:consequence>
       te = new Transaction(); 
       t.setActionName("red");
 
     </java:consequence>


However obviously then when this si called 
workingMemory.getApplicationData("t"), t does not hold the modified value. 


Thanks
