SYMPTOM:
 
Dropdown Selectors show as blank,  even when the "Automatically update when there is no data for the current selection" option is checked in Strategy Web 9.0.x, as shown below:
 
 
 
 
This issue can be seen when the target grid contains a view filter qualification.
 
STEPS TO REPRODUCE:
Follow the next steps to reproduce this issue in Strategy Tutorial Project:
 
 
 
 
 
 
 
 
 

• Create a report with `Customer Region`, `Customer State`, `Customer City` and  `Customer` in the rows and    `Revenue` in the columns.
• Insert the report created in step one in a Report Services Document.
• Create three  panel stacks inside the  document.
• Create four Dropdown selectors for `Customer Region`, `Customer State`, `Customer City`, `Customer`, as shown in the image below:
   
   
  

• Add the grid created in step one into the document  with formatting
• Select the three panel stacks (created in step 3) and grid in step 5 as target for the `Customer Region` selector, as shown below:
   
   
  

• Select the second and third  panel stacks from step 3 and the grid object created in step 5 as target for `Customer State` selector as shown in the image below.
   
   
  

• Select the third panel stack from step 3 and the grid from step 5 as target for the `Customer City` Selector as shown below.
   
   
  

• Select the grid  as target for the `Customer` selector.
   
   
  

• Make sure that all the selectors have the `Automatically update when there is no data for the current selection` and  `Show option for All` checked.
• Change the view of the document to `Editable Mode`.
• Select an element of customer region from the available selections. In this example, 'Northeast'. Note that the grid and additional selectors are updated as expected.
   
   
  

• Right click on the grid object created in step 5  and select  Edit View filter .
• Create a view filter  condition to use certain  'Customer State' elements as shown below.
   
   
  

• When attempting to change the selection for the 'Customer Region' selector, all other selectors will now display blank
