It is possible to inadvertently replace values of a name property in multiple selected components with ‘Multiple Values’.
Add two physics constraints components C1 and C2 to a blueprint.
In both C1 and C2 leave Component 1 name empty.
In C1 set Component 2 name to A.
In C2 set Component 2 name to B.
Select C1 and C2. Note that Component 2 name is shown as “Multiple Values”.
Set Component 1 name to X and hit tab. Focus jumps to Component 2 name.
Component 2 names are now lost. Drop selection and select only C1.
problem does not occur when hitting enter so focus stays on just edited property. However tab key is often preferred to enter as it is easier to access (no cross reach with left hand or letting go mouse with right one).
property with multiple values should not be updated when landing on control or leaving it with tab or enter. indication of multiple values should look different from the “Multiple Values” text: Lighter color, italic font, something which is obviously a message from editor and not actual data.
Thanks for report! I was able to reproduce this in 4.8.0 as well as our main internal build. I’ve entered a bug report for issue (UE-17013) and I’ll let you know here when I see any update on it. Thanks!
