This is on Hop GUI using the 1.1 release on Linux with OpenJDK Java 11.
When attempting to use this transform, the Select Keys new dialog will close out all other dialogs and fail to save any settings.
My particular pipeline is as follows for reproducing:
- Read from two separate tables in sqlitedb
- Sort rows on the same field ascending
- Send to multiway merge join
- Set input transform
- Set join type to either inner or full outer
- Click Select Keys
- Select any key field or Get key fields and then click OK
- All dialogs will close and will fail to save.
No errors are generated within the terminal where hop-gui was started. This prevents the transform from working at all.
