   [web] Flex change combo box selection
  I'm just wondering, say I have a combobox that's dataProvider is an HTTPService of xml like<users>  <user>  <id>1</id>  <name>eedok</name>  </user>  <user>  <id>2</id>  <name>testuser</name>  </user>  <user>  <id>3</id>  <name>testuser2</name>  </user></users>how do I specify for the combobox to select the user with an id of 2?Thanks   
  If you know that it'll be the second item, just use comboBox.selectedIndex = 1;Otherwise, get the object by parsing the XML: Working with E4XBy using something close to the example given, "(id=2)," you can retrieve the object with the given id.   ;  I forgot to mention the return value on the HTTPService is object and not XML so it comes back as an ArrayCollection so when I try do do E4X on it, I get this error: TypeError: Error #1123: Filter operator not supported on type mx.collections.ArrayCollection.Is there something similar for ArrayCollections?   ;  sorry for the double post, but I figured out how to change the selection by just looping over the ArrayCollection.Now I'm running into another issue, which I believe is caused by the one request finishing(setting the combobox selection) before a prerequisite request(binding the data to the combobox), is there any way to force a function to wait until another is finished before being triggered?   ;  This seems like an odd problem. Are you sure the HTTPService has returned the data when you bind it to the comboBox?   ;  This seems like an odd problem.
