Rule develop in 5.1

Description of problem:
We just start to usr JBoss BRMS 5.1 to develop some rules but we faced with this bug (https://issues.jboss.org/browse/GUVNOR-1335) so we tried to used the 5.2 version. But we faced an new problem. I attached a copy of the screen showing a rule developed with the 5.1 version and show after change to the version.

As you can see the part of the rule which use an Accumulate fonction is inactive (but the rule still valide according the validate function). Indeed, there's no more 'Number'  in the dropdown list box. The manual still present the use of Number in Accumulate fonction.

Version-Release number of selected component (if applicable):

How reproducible: try to develop a Accumulate function and you'll see.


Steps to Reproduce:
1. Make a model with a list or a set of objects.
2. Try to develop an accumulate function
  
Actual results:
Regression from 5.1, can't develop Accumulate function according to manual.

Expected results:
Use the accumulate function as usal.
