the list controls are very picky when it comes to ArrayCollections. In my code, I check to see if the length is 1 or gt than 1 and then set the dataprovider accordingly. To me, this is very much a PITA as now I have to add additional checks to make sure my data displays correctly.
FYI, I do not use XML, I use ColdFusion and Remoting. On 3/14/07, pdenys <[EMAIL PROTECTED]> wrote:
According to the Adobe Flex forum and Peter Ent of Adobe, I should use an XMLListCollection. Being simple-minded myself, I like simple things and hoped that an ArrayCollection and ComboBox would work. It seems to be a common example in Adobe docs (but fails when there is only 1 node of content which should give you 1 and only 1 item in your ComboBox). The XMLListCollection works fine when there is only 1 node of content in my source XML. However, I need to process the XML to get the "data" part of the ComboBox. I realize that I am not doing a good job explaining this.
