      Anyone know what this means?


      "an unexpected error occurred

      unable to get property 'length' of unidentified or null reference"


      I load a workbook to our local server. It shows some characteristics by race/ethnicity, by age, by education, by geographic region. The default shows the characteristics by all those groups. I log onto the server and when I deselect one of those groups from a drop down, a box pops up showing the unexpected error.


      Unfortunately the workbook is a work in progress so I can't include it here. But maybe some clues showing what this error means. I think I attached the box with that error. This error shows up if others open my workbook on our server from their desktops. I do NOT get this error if I open other workbooks on the server. So there is something about this file. I also have tried using various versions of Tableau, including 10.3, 10.4.0, 10.4.1 (our server is currently on 10.4.0). I have Windows 7. I also tried publishing the workbook with data "live" and with data "extract", didn't seem to make any difference, although I haven't tried live vs extract in all the different versions of tableau.
