KB46652: Toggling selections in the parent selector does not populate the child selector correctly in MicroStrategy Web 9.4.1

SUMMARY:
This issue has been classified as a defect by Strategy. The impact is limited to when upgrading to the Strategy Web 9.4.1 product while running a document with cascading selections. A solution/code fix for this issue is available for Strategy 9.4.1 Hotfix 3. There are some troubleshooting steps and additional information in the rest of this technote.
SYMPTOM:
A parent selector does not correctly populate the child selector after upgrading the dashboard to Strategy Web 9.4.1.
 
STEPS TO REPRODUCE:

• In a Strategy version previous to 9.4.1, create a dashboard with a parent selector and a child selector. Have the parent selector target the child selector.
• Associate attibutes in the same hierarchy to the selectors.
• Also create a panel stack that contains a grid that correspond to the selector attributes.
• Have the child selector target the panel stack.
• Run the dashboard in any of the view modes and the selectors should work properly, as shown below:
  

• Note: Selecting "Electronics" in the Category selector correctly populates the child Subcategory selector
  
• Upgrade the dashboard to Strategy Web 9.4.1.
• Now run the dashboard in any view mode, and the selectors will show a different behavior, as shown below:
  

• Notice: Even though there is a selection in the Category attribute, the Subcategory does not get properly filtered according to the selection.
  

 
CAUSE:
This is a known regression issue with Strategy Web 9.4.1. Code changes made in MicroStrateby 9.4 made to fix other issues changed the behavior of the selectors.
 
ACTION:
The fix for this issue is available in Strategy 9.4.1 Hotfix 3. Please upgrade to this version to take advantage of the fix.
 
ADDITIONAL TROUBLESHOOTING:

1. Toggle the Selector Type from Slice to Filter in the Selector properties.
2. Re-create the selectors from scratch.
3. Have the parent selector target the panel stack as well as the child selector.
