[UMG] Property Binding & "directly call the Set function"?

[anonymous_user_208e3372]

Hi, i have some questions about the [Property Binding][1] section in the UMG user guide where it reads at the bottom:

If you bind a property of a Widget and then directly call the Set function on that Widget, it will break the binding.

a) What does this in detail mean? does that mean i cannot call any Set function in the Graph Editor?

b) I have an issue with a property binding not working, here:

As you can see it is executing, but there is no visual effect. Maybe this is because i do call set some times in between - e.g. on the Selected variable?
The according widget is in a scroll box, which has already a bug ([Scrollbox isn’t really scrollable][4]) when used in a Vertical Layout, which i do despite the bug. Oh and also, the variables set in the property binding (New Visibility, Created Brush) are local ones, and i am still on 4.5.1.

What am i doing wrong, or is this a bug?

Well, got another approach running as i intended it. But also with another UE4 version (4.7-preview, might also work with 4.6.1), so i cannot confirm it fixed what i experienced.

And i still do not really know what is meant by the sentence i quoted above. I just assume that calling any set inside the property binding will fail.

But anyway, here is how i got it running:

Just use the select instead of a set and you are good, as it seems.

Since it fixed my issue, i will mark it as answered
