KB44591: "An Error has occurred on this page " error appears in the All Objects pane when using Tree View and executing a newly created report that uses shortcuts to reach the objects in MicroStrategy Web 9.4.1

SYMPTOM:
The Administrator configures a folder to be the highest level of the Blank Report template so that users creating new reports can only browse from that folder down. Then, the administrator uses shortcut objects to help the users navigate from that folder to a different one, like shown below:
 

 
If the All Object pane is displayed in tree view, and the user completes a report using an object taken from one of those shortcut folders in Strategy Web 9.3.1, they will get the error below upon execution:
 

An error has occurred on this page.

• Create a new folder in the Public Objects folder for the project in Strategy Developer 9.4.1
• Insert in this folder two shortcuts to other folders in any location, as shown below:
   
  

• Edit the Blank Report template or any desired template available under the Object Templates hidden folder in Strategy Developer, like shown below:

CAUSE:
This is a known issue with using shortcuts in the browsing root folder in Strategy Web 9.4.1. 
 
ACTION:
This issue has been addressed with Strategy 10.x. Upgrade to take advantage of the fix.
 
WORKAROUND:
To keep using tree view:
 
Change the root folder for the Report Web Browsing Options in the template to one that does not need shortcuts in the first level to get to the attributes such as the Schema objects folder, like shown below :

 
Now, when executing reports, they will not show the issue :
 

 
Otherwise, use List view instead.
