Are you using OE in your Rollbase? I noticed I'm using MySql and will test it using OE too, let's see if I can replicate it.
Ok got it!
1. I noticed in the first testing in the child list I added the parent column there <---- This works fine!2. I noticed in your testing you don't have the parent column in the child list <------ The issue occur!
Now in your setup try adding the parent into the child list column. See image below.
Hope this will help.
Nice spotting! Yes, adding the parent makes all the difference and works for me now too.
Thanks! I think Progress still need to look at it and fix it, but at least that works now :)
Again, nice spotting!
Yes, I will still file a defect regarding this, this need to be fixed.
