In the Pivot node, when trying to set the Grouping and Pivot column using variables there is often a problem.
It is possible to initially set the variables to control the columns successfully via Quickform nodes. However, once the user chooses a different column from the initial setup in the quickform nodes, when it gets to the Pivot node to apply the new settings, invariably this error is encountered;
WARN Pivoting 0:905:891 failed to apply settings: Loading model settings failed, caught "IllegalArgumentException": The include and exclude lists contain the same object.
When I go in and check the Pivot node settings and Flow variable settings, I can assure you different columns are being used for the Group and Pivot columns, and the include and exclude lists do not appear to contain the same columns to me.
Not off the top of my head, I tried a simple example and it seems to work fine, but maybe you are doing something slightly differently? Have a look and let me know if you see a difference.
thanks for taking a look, your workflow did work, but as soon as I added a second variable this is when all the problems started. I have attached a modified version of your workflow.
We identified the problem which we will fix for 2.9.2 -- released very likely next week. The underlying issue boils down to an invalid configuration caused by the variable assignment overwriting the exclude list while the include list contains the same value.
