Please post the entire Overview page - I see some other test code above the last block.
Makes it easier to me to find the error.
On my side it is working.
Thanks Oliver. Does seem to be working. Just have to get the Widget Props across
I guess that would be the next step?
I have cleaned up the Overview - TEST-2 page (there was a lot of work in progress stuff there):
Overview - TEST 2 Popup Test.txt (2.7 KB)
excellent. Now you ave the main concept created. And I see that this weird “back” is also gone.
And yes, now the real work starts 
- From here on, you could move the popup to its own widget. But be carefull, it might not be working as expected. Quite a while ago I intentionally built in the popup directly into the page as there were some problem. But I cannot remeber…
Just as a side note out of experience. I was at the same stage as you where I wanted to do everything with generic items and provide all required information either through props or be getting them from css sheets embeddeed into the page. To have reusable code and just to refer to a page-wide parameter for color or shading or buttonpressedlabelcolorsounds professional, but once the page is done that advantage is gone.
I ended up doing the opposite: To have multiple specialised widgets with as less props as possible.
