He was using remote services in Flex 2 to retrieve an array of structs from a cfc file to fill out a Flex combobox. The data was coming back and we typed it as an Array and everthing but the dropdown kept showing [object Object] instead of the correct label. We had the fieldLabel set correctly to match the param returned from the cfc service. What else could it be??

BINGO! I thought about how action script returns params from cfc services, all in caps. That was it, capitalization. Don't you hate those pesky bugs that turn out to be a tiny fly.

Rule no. 20ish something: Check params returned from cfc services in action script or mxml files to see if they need capitalization.
