Newbie report here. I hope it's helpful.
I think I found a bug in doing a column transpose in version 2.6-rc.2. I can accomplish the transaction in either 2.6-beta.1 or 2.5
Operating Systems and version: does not work in 2.6-rc.2 on Windows 7 and Windows 10.
Browser: on Win10: Chrome version is 51.0.2704.84
on Win7: Chrome version is 51.0.2704.84
Firefox version 29.0.1
Steps followed to create the issues
Transpose > Columnize by Key/Value Columns
Key Column = Location
Value Column = Category
Current Results: in 2.6-rc.2 I get the following error:
chrome: Index: 6, Size: 0
firefox: Index: 6, Size: 0
Expected Results: two columns transposed in 2.6-rc.2 as it does work in earlier versions
If this message should go somewhere else, please advise.
Looks like a duplicate of #1093 which is already marked for 2.6
fix #1138. column transpose
