while creating a component from sample in HAC, after selecting a sample, the create button was disabled for over 30 seconds and without any messages.
(See attachment for screen recording)

The wait time was extremely long, and from user experience point of view, I thought the created/detection somehow failed after I see a greyout create button and no feedback.
I saw the progress bar says "detecting sample component values" at the second I select a sample, but soon disappeared.

I'm assuming HAC is doing cdq and validation behind the scene to get the default values, but probably you don't need those values until the create button is being hit.

alternatively, should show some message to let the user know they should wait till the detection been done. or at least, the progess message "detecting sample component values" should not disappear.
