-----------------------------------
Summary: value property of NumericStepper does not update on text
input
Key: FLEX-33505
URL: https://issues.apache.org/jira/browse/FLEX-33505
Project: Apache Flex
Issue Type: Bug
Components: Spark: NumericStepper
Affects Versions: Apache Flex 4.9.0, Adobe Flex SDK 4.6 (Release)
Reporter: Chris Martin
If a user changes the value of a numeric stepper, they must focus on an
different UI element for the change to propogate down to the value property.
I'll attach example code that demonstrates this behavior. The application is
simple. User clicks on a button to present a popup with a numeric stepper in
it. When the popup closes the label just to the right of the button gets
updated with the NumericStepper.value property
Steps to Reproduce
1.) Click on the button
2.) Click into the NumericStepper and type in a new value
3.) Close the popup
Result
The label is not updated with the appropriate value
Expected Result
The label is updated with the value that was typed into the NumericStepper
Workaround
You can get around this by detecting if the NumericStepper.textDisplay.text
does not match the NumericStepper.value, if so then assume the textDisplay.text
value is the right one and use it. This is not a good workaround as it
requires an assumption and any updates to how the text value gets formatted
into a numeric value in the component will not be carried over in the custom
work around.
To Force expected behavior you can do the following:
1.) Click on the button
2.) Click into the NumericStepper and type in a new value
3.) Click into the TextInput
4.) Close the popup
When the NumericStepper loses focus, then the appropriate update functions are
called in the component to update the value property
