Performance Management EL expression code

Content

Where can I get the Task code for the performance management for writing EL Expression customizations in performance management pages.

For example consider the following EL Expression:

#{!pageFlowScope.pReadOnlyRatings and

pageFlowScope.pSectionTypeCode == 'GOAL' and

pageFlowScope.pRoleTypeCode ne 'PARTICIPANT' and

pageFlowScope.pTaskCode =='CONFCRIT' }

Where will I get p.TaskCode complete list.
