Question

I use httpservice with object result to load data on dropdownlist.
Some time the result is only one element. In this case, an error appear. I know that another solution is to e4x result format but I think that in this case it’s longer.
So if someone could help me?

Thanks

You can either change the service to always return a collection or you will have to do a preemptive casting in Flex.

In Flex,

• cast the result as :*
• use result.hasOwnProperty(“source”) or similar.
• if true, you have an array collection, cast as array collection and resume
• if false, you have a string or just the one item. Cast it and resume.

Hope this helps.
