Link combo boxes

Hi all,

I’m writing a flex app which takes in something like the following xml

[COLOR=red]<VersionList>
<Version>
<Release name=“7.11.0”>
<Snap name=“S05”/>
<Snap name=“S11”/>
<Snap name=“S12”/>
<Snap name=“S14”/>
</Release>
</Version>
<Version>
<Release name=“7.12.0”>
<Snap name=“S12”/>
<Snap name=“S19”/>
<Snap name=“S28”/>
</Release>
</Version>[/COLOR]
[COLOR=red]</VersionList>[/COLOR]
[COLOR=#ff0000][/COLOR]
[COLOR=black]I have 2 combo boxes - 1 which holds the version release names and another which holds the snap names![/COLOR]
What I want to do is populate the version combo box and depending on what is chosen, populate the snap combo box
Ex: if the user selected 7.12.0 - the snap box would display s12, s19, s28!

I have my mxml file set up to take in the xml file and load the release names into an array to populate the version box! Does anyone know how I could populate the snap combobox depending on what is chosen in the version box???

Thanks a mil in advance, any help would be greatly appreciated!

Cheers,
Derm
