DateField selectedDate and text issue

[Manik Magar <ma...@gmail.com>]

Hi All,

While working with DateField, I observed below behavior, is it a bug? If
yes, should be it be logged to Apache JIRA or Adobe bug database and Can I
put a fix for it in SDK?


Assume a Datefield added on some application -

<s:DateField id="dt"/>


on some button click i have below code -

dt.selectedDate = new Date();
Alert.show(dt.selectedDate);   ---- This alerts todays date
Alert.show(dt.text);   ---- alerts todays date

dt.text = "";

Alert.show(dt.text);   ---- alerts ""
Alert.show(dt.selectedDate);   ---- This still alerts todays date.


Now, if you open a datefield in front end to select a date, selectedDate
gets reset to NULL because text is set to "".
text will reset to "" if selectedDate is set to null, then why not
vice-versa?

Shouldn't this happen as soon as you set text = ""?

That is expected behavior because most components use invalidation.
Changing a property programmatically isn't guaranteed to change computed
properties without time to validate or a call to validateNow().
