Summary

User has two applications (For example, Application A: Build on Customer Process Manager (CPM) and Application B : Not Build on CPM). The application is switched when the user switches from Application A to Application B. However, the data page continues to search for the data transform of Application A instead of going to the activity of Application B.

Error Messages

Failed to find Rule-OBJ-MODEL with the name Activity that applies to Class. There were 3 rules with the name in the rule base class but none matches this request.
 

Steps to Reproduce

1. Create two applications, Application A and Application B
2. Implement the out-of-the-box Switch Application logic
3. Create two data pages in both the applications with a same name
4. Configure a data transform in the data page of Application A
5. Configure an activity in the data page of Application B
6. Log in to Application A and switch to Application B
7. Initialise the data page. The data page uses the Application A context and the error occurs

Root Cause

The mode of both the data pages is Read-only and the scope is Requestor. A Read-only data page pre-loads and it cannot be updated.
