v6.17.0: Edited values do not "stick" without tab or enter

For example, if I edit the ‘Synchronous Predivider’ value for the STM32F030 RTC:

 

Then, say, click on TIM1:

 

Then go click back to the RTC view:

 

My edit is gone!

 

I’ve also been caught-out with this on UART baudrate.

I suspect it applies to any numeric-entry field.

 

This should, at least, ask if I want to lose edits.

 

On Win11-Pro.

    this is the way MX works by design.

    Then it is a poor design!

     Another example - I have typed-in a new ‘Synchronous Predivider’ value:

     

    If I then click on the ‘Tamper 2’ checkbox, it gets enabled - but, again, my edit is lost:

     

    However, if I edit the ‘Synchronous Predivider’ value, and then click into the ‘Asynchronous Predivider’ box - my edit is not lost!

    Hello ​@Andrew Neil 

    Could you please try to use the latest version of STM32CubeMX6.18.1?

    And please make sure to press “Enter “ after editing the field.

    And please make sure to press “Enter “ after editing the field.

    That is my entire point - we should not have to worry about that !

      Hello ​@Andrew Neil 

      This is the expected behavior in MX: edited values are only committed when you validate the field, typically by pressing Tab or Enter. If you click away or continue without validating, the change may not be applied.

      So in short: this is the way MX works by design.
