I'm currently migrating from a 360 version to the last 361 (with globalqss patches).
I've made some tests and i found out that Display Logic is mostly broken in swing mode.
When a param should be hidden, the field is hidden but not its "heading".
You can try with process "Bill of Material & Formula Cost".
Put something on Product Category.
Field "product" disappears, but no the heading.

It was working properly in 360.
WebUI is ok.
Thanks,
Yan
