Nested presentation not functioning

I have a presentation (call it Main screen) that has one primary placeholder (Main Presentation Area) as well as other placeholders that function fine. The Main Presentation Area consists of a single placeholder & presentation (Main Presentation) that pulls from another 'company's' area (the sub-company is just access control for staff).  In the companies presentation area, the Main Presentation includes just one placeholder that has some content as well as another a presentation (Sub-presentation).  The Sub-presentation consists of a text item and the placeholder has a background image applied - The image is hosted on my own website and other images from my website show fine.

The Sub-Presentation previews wonderfully, but does not show in the Main presentation preview or the Main Screen preview - just showing a blank box without the text or the image. I've reduced the other content in the Sub-Presentation to just one other item and the content functions but not the Sub-Presentation. I have set all the items/presentations/placeholders to timeline 'All' and display 'All'.

I'm at a loss as to  why it shows on previews, but does not display when nested.

If I simplify this nested mess and change the "Main Presentation Area' placeholder to only show  the Sub Presentation directly, is still does not work.

Help?

Ah - I found the issue!

In my sub presentation, I had two place holders both the same size and shape directly overlapping each other.  

In one place holder (in front) I'd placed the Text Item and made the background of this placeholder a dark tint (40% black)  In the second placeholder (in back), I made the background an image with no content. By doing this layering, I could overlay white text onto a darkened photo without changing the photo itself.  

If I change this to be image content with no background, or if I create a text placeholder with no content, it works.  But having a placeholder, with a background, but no 'content' previews fine, but breaks when nested.

Bug or feature?

Hi Ben,

I'm hoping I follow along here. 
  • Main presentation w/mostly working content
  • Placeholder with an embedded presentation item, the embedded presentation is from a sub-company.
  • Embedded presentation only consists of an image item and text item.
Is this correct? If so, my first step would be to open a preview tab, open chrome developer tools, and take a look at the console view. See if there are any blocked or not found error messages.

Another thing to check for would be to make sure your presentation is published with the new changes you have made. Quite often I'm making changes and totaly forget to publish!

Yes - it was published.  Of course, after I post, I find the problem.  It seemed to not like the placeholder without content when using the background setting.  Placing a blank text item or moving the image to an image item (instead of using the background setting) fixed this whole mess.

Ben,

Glad you were able to work it out! We don't really take a look at community member's presentations anymore, but I was intrigued and about to make an exception. Please let me know if you continue to have any issues.

Glad to know my setup is so odd!  I always assumed that most people who use sub-companies will have presentations nested at least 3 deep.

Nonetheless, I think it may be a bug that a presentation that includes a placeholder that has no content (but does have a background setting applied) will preview fine, but might prevent the entire presentation from displaying if nested inside another presentation.

Ben,

I'm going to take a look at your presentation and log a bug if needed. Thanks for the heads up!

Note, I've of course fixed mine - But if you delete the empty text item inside of the 'background_image' placeholder in the 'Snow Day' Presentation of the Staff Sub company you should recreate the issue when previewing the 'Presentation Area' in the sub-company or from the Main Display of my main presentation area.
