Not able to create data table with value list column
SA-891
Summary
User trying to create a table having column with property mode as value list using Data Model - Data Tables wizard, in pega 7. It is throwing an error
Here we are creating value list property, not referencing to any particular value in value list. So there is no need to provide index value.
Error Messages
Errors:
** An index value is missing in a reference to a valuelist or valuegroup: .test. Please enter an integer value/valid name.
.pyUI.pyBody.pyUIFields(2).pyFieldName: This is not a valid property, or this is a property that cannot be used here.
pyClassName:** ** An index value is missing in a reference to a valuelist or valuegroup: .test. Please enter an integer value/valid name. .pyUI.pyBody.pyUIFields(2).pyFieldName: This is not a valid property, or this is a property that cannot be used here.
Steps to Reproduce
1. Open Datatable wizard and give the class which is inherited from data-
2. Define the columns ID, pyLable, and DocumentList (which is of Vlauelist mode)
3. click on generate.
An error will appear on the screen.
Root Cause
The root cause of this problem is a defect in Pegasystems’ code/rules.
Below validation is causing the problem.
@(Pega-RULES:Property).invokeValidate(.pyFieldName, IsFieldAProperty)
IF Validation of .pyFieldName using IsFieldAProperty fails
THEN display message:
IsNotAValidField
ValidatePropertyName validate rule is invoked.

Resolution
As a workaround to this problem till you upgrade, the change would be to include the below When condition on the activity pzGenerateRD’s STEP 3.
.pyPropertyMode=="StringList"
This would make sure that the stringList/ValueList is addable to the created DataTable.
This issue is scheduled to be resolved in Maintenance Level (ML) release ML 7.
