Hi All!

I have ComboBox in state and when I change its dataProvider, where
labels are longer, its dropdown size doesn't change. I attached two
application files and you can also find their source below. Click
"Edit" button first, then "Cancel" and "Edit" again. Dropdown is so
thin.

Test.mxml:

<?xml version="1.0" encoding="utf-8"?>
<TestBase xmlns:mx="http://www.adobe.com/2006/mxml";
        xmlns="*"
        currentState="viewState">

        <states>
                <mx:State name="{VIEW_STATE}">
                        <mx:AddChild relativeTo="{myHBox}" position="lastChild">
                                <mx:target>
                                        <mx:Button label="Edit"
click="onEditButtonClick()" />
                                </mx:target>
                        </mx:AddChild>
                </mx:State>
                <mx:State name="{EDIT_STATE}" enterState="onEditStateEnter()">
                        <mx:AddChild relativeTo="{myHBox}" position="lastChild">
                                <mx:target>
                                        <mx:ComboBox id="myComboBox"
dataProvider="{[1, 2, 3]}" />
                                </mx:target>
                        </mx:AddChild>
                        <mx:AddChild relativeTo="{myHBox}" position="lastChild">
                                <mx:target>
                                        <mx:Button label="Cancel"
click="onCancelButtonClick()" />
                                </mx:target>
                        </mx:AddChild>
                </mx:State>
        </states>

        <mx:HBox id="myHBox" />

</TestBase>

                        currentState = VIEW_STATE;
                        myComboBox.dataProvider = ["Italy", "France",
"Germany"];
                }

                protected function onEditStateEnter() : void {
                        if (myComboBox.initialized) {
                                onEditState();
                        } else {

myComboBox.addEventListener(FlexEvent.CREATION_COMPLETE,
onMyComboBoxCreationComplete);
                        }
                }

                private function onEditState() : void {
                        myComboBox.open();
                }

                private function onMyComboBoxCreationComplete(event :
FlexEvent) : void {
                        onEditState();
                }

        }

}

Thank you in advance!

Regards, Sergey.
