Cory Bear commented on FLEX-33684:
----------------------------------
Here is an open source alternative which works like the <s:ComboBox> except
without several bugs including the one described in this ticket:
https://github.com/pdpsolutions/px/blob/master/visual/BindableComboBox.mxml
> Only one 'custom' text entry can be enterred in a spark ComboBox
> ----------------------------------------------------------------
>
> Key: FLEX-33684
> URL: https://issues.apache.org/jira/browse/FLEX-33684
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: ComboBox
> Affects Versions: Apache Flex 4.9.0, Apache Flex 4.10.0
> Environment: Windows 7, Intel i5, 4GB RAM
> Reporter: david bel
> Fix For: Apache Flex 4.10.0
>
>
> The spark combobox allows the user to enter a 'custom' text entry, ie an
> entry which doesn't match any label from the data provider.
> However, the first such 'custom' item entered appears to get stuck in the
> control, until an item from the list is selected.
> Steps to reproduce:
> Compile and run the following simple application:
> <?xml version="1.0" encoding="utf-8"?>
> <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009";
> xmlns:s="library://ns.adobe.com/flex/spark"
> xmlns:mx="library://ns.adobe.com/flex/mx">
> <s:Group>
> <s:layout><s:HorizontalLayout /></s:layout>
> <s:ComboBox id="myCombo" width="200" >
> <s:dataProvider>
> <mx:ArrayList>
> <fx:String>test1</fx:String>
> <fx:String>test2</fx:String>
> <fx:String>test3</fx:String>
> </mx:ArrayList>
> </s:dataProvider>
> </s:ComboBox>
> <s:TextInput id="myText" width="200" />
> </s:Group>
> </s:WindowedApplication>
> Click in the combo box and type "abc"
> Tab out of the control or click in the text input to change the focus.
> Click in the combo box again, and now type "xyz"
> Tab out of the control again or click in the text input to change the focus.
> Actual: The text input control of the combo box now contains "abc"
> Expected: The text input control of the combo box should contain "xyz"
> I wrote a short patch for this, but it is by no means a proper or long term
> solution:
> public class PatchedComboBox extends ComboBox
> {
> public function TestComboOverride()
> {
> super();
> }
> override protected function
> focusOutHandler(event:FocusEvent):void
> {
> applySelection();
> super.focusOutHandler(event);
> }
> }
> The problem doesn't really lie with the handling of the focus out event, but
> rather, I believe, with a bug fix for a different though related issue (see
> ComboBox.as @ 895):
> The setSelectedIndex method is overwritten to handle a special series of
> events which may cause the selection of an item to be ignored. However, this
> fix ignores the fact that the user may have entered a second text value.
