Issue

When changing a Multiple Values (dropdown) filter selection on a dashboard from selecting none of the values to subsequently selecting a single value, an unexpected message occurs:
 
"Unable to Complete Action: Table Arrays Must be of the Same Size"

Environment

  • Tableau Desktop 2018.2 - 2018.3

Resolution

Option 1

Upgrade to Tableau Desktop 2018.2.3, 2018.3.1 or a newer version. For more information, see Upgrade Tableau Desktop.

Option 2

Customize Filter to Show Apply Button on the dashboard filter to ensure that the view is never blank (with all options deselected). For more information, see Customizing Filter Cards

Note: The purpose of the Apply button is to give the end user the ability to select/deselect filter options without having the view automatically update to blank when deselecting all options.

Option 3

Use Tableau Desktop 2018.1

Note: If your workbook was upgraded to version 2018.2, you can export it as version 2018.1 by following the steps below:
  1. Open workbook in 2018.2
  2. Navigate to File > Export as Version > 2018.1

Cause

This behavior is related to a known issue, ID 817682, which was corrected in version 2018.3.1.
