Hi,
Inside "Dynamic Attributes" adding a second "Class Toggle" in any object cause that both "Class Toggle" show up empty.
Normally with one "Class Toggle":
Its same inside/outside a repeater, or alone, or inside/outside a form or div.
Note, the error is only in UI, the code show up correctly with both dmx-class tags.
More data:
If adding by code the second "Class Toggle" the UI show up correctly both "Class Toggle".
If adding a third "Class Toggle" the second one get delete by the UI the first one keep showing.
In all cases the code show up correctly.
I have the same issue on 6.8.0, when you add another class-toggle it blanks both class-toggles in the UI but the original one remains in the code. When you add a second one, it correctly adds the correct code but duplicates the class name in the UI
Unfortunately i can't recreate the issue.
Have you tried to refresh the App Connect tree when the class toggle disappears or click on some other element and then back on the input?
Also - does it only happen in Code view?
I tried refresh and that makes no difference, also happens when in design view only. I think it may be related to other components on the page potentially as it seems to work ok on a new page
I did use Design View before, I just had the code view open to show that design view UI was not the same as the code view.
There do seem to be a few quirks as per your bug with the expression builder, I have gotten into the habit of copying the code generated in the expression builder in case it doesn't save the changes.
