Resolved Issues

Issue ID Description

When you used a regular expression containing a backslash (\) in a calculation in Tableau Prep 2018.2.3, the calculation returned incorrect results.


When using custom SQL in Tableau Prep, having any text between a less than sign resulted in the error "Error in input "Custom SQL". Can't connect to datasource . An error occurred while communicating with the data source. Custom SQL relation refers to a non-existent parameter..."


Sometimes, Tableau Prep stopped responding while adding a step.


After performing different pivot steps on the same dataset as well as multiple joins, the "group and replace" function is not working on a subset of the field values within the same column. Red dots next to those field values indicate that those values are not contained in the dataset, when in fact they are. 


Sometimes, Tableau Prep quit unexpectedly while joining tables.


Flow file fails to run in Tableau using "tableau-prep-cli.bat" command, when a .hyper file is used as data source and Tableau Server is destination for the published output.


When you tried to publish a flow to an SSL-enabled Tableau Server, a blank start up page displayed and the flow failed to publish.


In flows with multiple joins and self joins, sometimes there was no data shown in the Profile pane, and an "IllegalStateException" error occurred when clicking a step.


After changing the data source for an input step, saving a .tflx, then opening a .tflx in Tableau Prep 2018.2.3, sometimes fields were missing starting from the first Clean step in the flow and errors appeared throughout the flow.
