> Key: FLEX-22735
> URL: https://issues.apache.org/jira/browse/FLEX-22735
> Project: Apache Flex
> Issue Type: Bug
> Components: mx: DateField
> Affects Versions: Adobe Flex SDK 3.4 (Release)
> Environment: Affected OS(s): Windows
> Affected OS(s): Windows XP
> Browser: Internet Explorer 8.x
> Language Found: English
> Reporter: Adobe JIRA
> Labels: easyfix, easytest

> The problem arises when a date in the datefield is updated by some
> programmatic logic that rechanges the selected date based on its value. The
> programmatic change is not reflected in the datefield when the date is edited
> in the text field (not changed using the choosed).
> Using the attached demo:
> 1. Click the master date chooser and select a date. Both datefield boxes show
> that the date displayed is the one chosen plus one day (the programmatic
> change). Everything is fine here.
> 2. Now, change the date in the textfield, not using the chooser and tab out
> of the field to submit the changes. The slave field shows the new correct
> value, but the master does not.
> This is because the focus_out_handler in the datefield processes before
> commitProperties when the selectedDate value is set (by binding or
> programmatically after it changed). Thus, when the updated selectedDate is
> set, the focus_out_handler resets the internal value of _selectedDate to the
> value of the textField ( which is the old value) before commitProperties
> processes the updateDateFiller flag. By the time it processes the change, the
> focus handler has reset the new selected date to the old value in the text
> field.
> It seems to me that, in the selectedDate setter, the line:
> dateFiller(_selectedDate);
> should be added after:
> updateDateFiller = true;
> This should cause no problems in commitProperties since the updateDateFiller
> flag is processed after the selectedDateChange, so if anything (other than
> the focus handler) has changed the selected date prior, it will still be
> reflected in the textfield. We just beat the focus handler to the punch.
> Workarounds:
> Extend the datefield and override the selectedDate setter to update the
> textInput field text immediately instead of flagging updateDatefield which is
> handled in commitProperties():
> override public function set selectedDate(value:Date):void
> {
> super.selectedDate = value;
> dateFiller(_selectedDate);
> }
> and copy the private dateFiller function into the extended DateField.
> Everything works correctly now.
