Flex 3.5.0; Update ComboBox display list upon dataprovider change
- by Gabriel Poama-Neagra
Hello,
I have two related ComboBoxes ( continents, and countries ). When the continents ComboBox changes I request a XML from a certain URL. When I receive that XML i change the DataProvider for the countries ComboBox, like this:
public function displayCountryArray( items:XMLList ):void
{
this.resellersCountryLoader.alpha = 0;
this.resellersCountry.dataProvider = items;
this.resellersCountry.dispatchEvent( new ListEvent( ListEvent.CHANGE ) );
}
I dispatch the ListEvent.CHANGE because I use it to change another ComboBox so please ignore that (and the 1st line ).
So, my problem is this: I select "ASIA" from the first continents, then the combobox DATA get's updated ( I can see that because the first ITEM is an item with the label '23 countries' ). I click the combo then I can see the countries.
NOW, I select "Africa", the first item is displayed, with the ComboBox being closed, then when I click it, the countries are still the ones from Asia. Anyway, if I click an Item in the list, then the list updates correctly, and also, it has the correct info ( as I said it affects other ComboBoxes ). SO the only problem is that the display list does not get updated.
In this function I tried these approaches
Converting XMLList to XMLCollection and even ArrayCollection
Adding this.resellersCountry.invalidateDisplayList();
Triggering events like DATA_CHANGE and UPDATE_COMPLETE
I know they don't make much sense, but I got a little desperate.
Please note that when I used 3.0.0 SDK this did not happen.
Sorry if I'm stupid, but the flex events are killing me.
