KB46880: Multiple elements are highlighted when using an attribute with compound key as a selector in Visual Insight and MicroStrategy Web 9.4.1.

SYMPTOM:
 
In Visual Insight in Strategy Web 9.4.1, an attribute in a grid can be used as selector to target other grids in the same dashboard. When the attribute used as a selector has a compound key, i.e. multiple attribute forms conform the ID form, any element that matches at least one of the ID's will become highlighted, like shown below.

 
Selecting Aadland Constant, will also highlight Aadland Miko and Aadland Warner. The expected behavior is that only the element whose compound key matches on both of the ID forms is highlighted and not the ones that match just one of them.
 
STEPS TO REPRODUCE:

• Copy the customer attribute in the Strategy Tutorial Project.
• Make the First name and Last name DESC forms into the ID form.
• Then, delete the ID form and all parents/children as seen below:
  

• Place this new attribute in a report.
• Create a Visual Insight Analysis with it.
• Add the customer attribute to the rows and add in an additional grid object to the layout.
• Set this layout to be used 'as filter', like seen below:
  

• Under Filtering Options, select "Grid", "Enable filtering on selection", and 'Allow users to clear all selections", as seen below:
  

•  Click on any element where the Last Name form repeats, such as Aadland, and notice that all elements with the last name Aadland become highlighted.

CAUSE:
