3222339 - Error on Executing Validation Business Rule


The requirement is to have a validation rule so that information from grid portlets such as National ID, Email, Phone Information or Job Relationships, etc. is always present/cannot be deleted.

But the rule does not popup any message upon deleting the concerned values/records.

By downloading rule trace we see it fails: "Error: Collection Filter can only be applied to a collection, not class"

Similar rules work when used Employee Information Base Object and executed in Add New Employee.

Reproducing the Issue

Sample scenario:

  1. You create a Business Rule for base object: Job Relationships;
  2. The rule should throw an error if Name field is Null;
  3. You add it as onSave in employmentInfo, in BCUI;
  4. Navigate to an employee's profile;
  5. Go to Job Relationships portlet, delete all the existing entries and expect that upon save, the rule will get triggered and the error message will display;
  6. However, nothing happens and the changes are successfully saved;
  7. When you download the Rule trace you notice the following error: "Error: Collection Filter can only be applied to a collection, not class com.successfactors.hris.bean.eo.EmpJobRelationsEO".


On grid portlets, it is not possible for a business rule to be executed when its base object is null.


As per the current product design, this is only supported for New Hire scenarios.
