Designer Display Component

Good evening.
A made a copy of a project, but when i turn on the "display hidden component" in the designer, don't appear nothing, although the scrollable flag is selected.
How i can resolve this problem?

Thank you, this has been reported and passed up the line on several occasions.

Is there a solution?

There is a new version of AI2 under test at

Try it there, and let the thread know if it helped.

I wouldn't use ai2-test for development, though.
There's no backward compatibility because it's a new component release and it's just for testing releases, with no project safety.
