    Web data connector in tableau server

    vijay reddy

      Hello All,

       

      I have developed a web data connector for tableau. It works fine with tableau desktop.

       

      I have issues using it on tableau server.

       

      case 1:

       

      1. I connect to web data connector, create a sheet and add visualization

      2. Publish the workbook. so the connection is also published.

      3. Create a new tableau document, use the published connection, things work fine

      4. open the workbook in tableau server and things work fine.

       

      case 2 :

       

      1. I connect to web data connector

      2. publish the connector alone

      3. create a new tableau document, use the published connection. Now i see the Live connection option is enabled. Now with the Live connection, if i try to create a visualization, it throws up an error "No such function SUM that takes arguments of type (real)", if i use a measure in the chart. If i use a dimension then things work fine

      4. create a new workbook in tableau server and I get the same error.

       

      Is live connection not supported in this case? is there a way to get this working?

       

      Any help here is appreciated.

       

      PS : I have done the basic things like white listing the url etc.

      I also tried to convert the data type using float(), still get the same issue.

       

      Thanks
