Subject [jira] [Commented] (FLEX-20) The Max value restriction in Spark NumericStepper doesn't work properly

Pierangelo Mancusi commented on FLEX-20:

Hi John,
fist of all, nice to meet you.

let's start the answer:
your comment  to the  issue at Adobe site is wrong, cause it's based on a bad interpretation
of the issue.
Of course, before i started to work on this, i tested your solution but it was wrong. (i compiled
the SDK with your suggestion...btw thanks Justin for your  good work )

When the component is created passing nothing to the "value" property, it inherits the property
"value=0" from the Range.as class (if you assign a numeber, the component takes it obviously).

when we change the value in the component, the TextInput.text is passed to the NumberFormatter.parseNumber(parseString:String)
( see line 796 - NumericStepper.as)

This last help method return NaN and the property lastOperationStatus of NumberFormatter class
 is set first to "illegalArgumentError" and then to "parseError".

Here is the mistake and the question is: When we can insert a "NaN" value in the NumericStepper's
TextInput, which accepts  only strings rapresenting a number?...never i say.

so when  NumericSteppes's  inputValue is NaN, after all possible assignement in that method,
 i restore the last valid value.

that is the fix.

Also i 100% agree with you  when you say that the comparison at line 791 of the NumericStepper
class  is rather questionable.
Never seen an if like that :)

>         Environment: Apache FlexSDK 4.6 - Adobe FlexSDK 4.6 -  Adobe FlexSDK 4.5

> original issue: https://bugs.adobe.com/jira/browse/SDK-31123
> here a summary:
> Steps to reproduce: 
> 1.Launch the browser with Numeric stepper. Set the min value as 10 max value as 50. Also
set default values as 20. 
> 2.After launching the broswer clear the default value 20 and focus out from the numeric
stepper. It displays "NAN" 
> 3. Again focus back to the numeric stepper and try to edit 3 digit value (Eg.777). Then
foucs out. It doen't restrict to max value i.e"50" as set earlier in 
>    step 1. It allows the 3 digit value enetered instead. 
>  Actual Results: The enetered value will be displayed 
>  Expected Results: It should restrict and display the max values as set in step 1. 
>  Workaround (if any): No Work around.
