Hi Michael,
I created a sample at jsbin.
However, it works fine there.
As my application is rather complex and is not accessible via a public link, I don't know whether I can provide a non-working sample.
I can try to describe what's happening using the example above.
I click at the "CLICK HERE". The SelectDialog opens, uses the full height of the screen (600 px), and it looks just fine. However, a few milliseconds later (after rendering the SelectDialog), the height of the SelectDialog changes to 2000px.
It seems like height calculation doesn't work for my application, but I don't know why. Is there anything special for the SelectDialog which my application may prevent the height calculation?
I can open a customer ticket when required. However, I would not be able to send you more details compared to the public forums here.
Thanks for investigating this issue, as it drives me crazy.
Regards
Tobias
