Hi Marcus,
Thank you for your replying.
OK, I'll try to create a project to figure it out.
However this problem was found by my colleague, and she is busy in these
days.
Please give us a little more time to do it.
When we get the programs, I'll try to entry an issue into the site which you
give us.
Best regards
Yusuke Masuda

Subject: Re: We faced a TypeError in using ComboBox.
Hi Yusuke,
can you create a very small test project with this issue? If you think this
is really an issue you can file any issues here:
https://issues.apache.org/jira/browse/FLEX and you can attach the test
project to this bug (swf file / FXP file)
The mailing list is not the best way to file issues.
Best regards
Marcus

Hi, all.
I'm getting a trouble using 'mx.controls.ComboBox'.
Could you help and give us a correct code.
I got an error 'TypeError: Error #1009' when I clicked a combobox on
inactive window. [see stack traces below]
So I checked the source code, and I'm afraid that it's a kind of program
bug.
We are using a custom ComboBox that extends 'mx.controls.ComboBox' which
is made by ourselves.
Though the error has occured on the component, it occur in not only our
ComboBox, but also 'mx.controls.ComboBox'.
The immediate cause is a variable 'tween' is null (not initialized) at
line:1912 of ComboBox.as.
When I clicked the ComboBox, a method 'displayDropdown' is running.
Then a variable 'inTween' get change to 'true' when the process has come
to line:1871.
And a method 'UIComponentGlobals.layoutManager.validateNow()' is called at
line:1877.
After that an event 'styleChange' has fired, and 'destroyDropDown' is
called from an event handler 'styleChanged' at line:1416
In 'destroyDropDown', a code is calling 'tween.endTween()' after 'inTween'
checked, but 'tween' is not initialized yet.
The 'tween' is initializing in a method 'displayDropdown' at line:1890
after calling 'UIComponentGlobals.layoutManager.validateNow()'.
So 'tween' still has been null.
We are thinking the code should be changed from "if (inTweet) " to "if
(tween != null && inTween) {" at line:1919.

* This stack traces which we got while using Adobe Flex 4.6.

It's the first time to send to mailing list and I'm not good at English.
Please excuse me if you may not understand or you feel bad with my poor
English.
