Unable to refer a property of parameterized data page in section



Error occurs when referring a property of the parameterized data page in a control source. However, this works when referring a a non-parameterized data page.

Error Messages

Invalid property reference

Steps to Reproduce

  1. Configure a section to use a repeating grid layout
  2. Source the grid with a parameterized data page 
  3. Configure a property in the repeating grid to use the format D_WorkList[Param.OperatorID].pxResultCount to refer any property in the data page
  4. Run the case

Root Cause

This is a limitation in the product to refer the parameterized data page in only few rules. The D_DataPageName[param1:value,param2:value] syntax is supported in only the following rule types: 
  • Rule-Declare-CaseMatch 
  • Rule-Declare-DecisionTable 
  • Rule-Declare-DecisionTree 
  • Rule-Declare-Collection 
  • Rule-Declare-Constraints 
  • Rule-Declare-Expressions 
  • Rule-Obj-Activity 
  • Rule-Obj-Batch 
  • Rule-Obj-Model / DataTransform 
  • Rule-Obj-When 
  • Rule-Parse-Infer 
  • DecisionMap 
  • FunctionAlias 
  • PropertyAlias 
  • Strategy 
  • Scorecard 
  • Interaction 


Perform the following local-change:
  1. Create another list and copy all the contents of the data page to the list
  2. Refer the list as the property source for control in the section
