I exported a Project "A" over a month ago.
Later. I duplicated the Project "A" and created Project "B".
When I viewed the duplicated Project "B" in the Designer
- I selected a Tab Element... and the Tab itself - disappeared.
This was not the expected outcome.
The expected outcome... was a specific / targeted DIV (map-dir-4 and directions-tab-4) being hidden... not the Tab itself.
In reviewing the Objects Tab / Interactions Panel...
- I found 2 interactions were not referenced properly.
--- note both "Click (1 Step)" interactions...
and compare it to the code (further below) which DOES contains the reference to "map-dir-4" and "directions-tab-4".
Here - I exported Project "B" and compared the JS files on both Project "A" and "B".
The code was exactly the same and the code contained correct reference.
Therefore... when exported - the site runs properly.
But in preview mode... it does not run properly.
AGAIN - When I EXPORT the project... it DOES export the correct reference.
But in PREVIEW MODE... the Designer does not see the correct references.
And therefore... executes the wrong wrong instructions
- resulting the Tab itself disappearing - instead of the targeted DIV.
The bug is in the Designer.
