Mark Proctor resolved JBRULES-2771.
-----------------------------------

    Fix Version/s: 5.2.0.M2
                       (was: 5.2.0.M1)
       Resolution: Out of Date


I believe this is fixed. This was becaused named partitions other than default did not implement TMS. That is no longer true and ALL partitions now use the same codebase. Please let me know if it's still a bug

> This sequence of statements disagrees with the documentation:
>     WorkingMemoryEntryPoint entryPoint = kSession.getWorkingMemoryEntryPoint( "epn" );
>     FactHandle fh = entryPoint.insert( fact );
>     kSession.update( fh, fact );   // should be done using entryPoint.update
> But this causes (in 5.1.1) a NPE
> Exception in thread "main" java.lang.NullPointerException
>     at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1379)
>     at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1338)

>     at event.Main.execute(Main.java:153)
>     at event.Main.main(Main.java:164)
> This is the line:
>    if ( this.maintainTms ) {
>                 status = ((InternalFactHandle) factHandle).getEqualityKey().getStatus();
>   }
> and similar code can be found in trunk, so I suppose this is still possible.
