Passing an ArrayCollection from ColdFusion to Flex (with BlazeDS)

Question

When pushing objects from ColdFusion to Flex via BlazeDS, and mapping the classes using RemoteClass...

[RemoteClass(alias="blah.blah")]

...is it possible to have ColdFusion "Arrays" (or some Java equivalent) automatically mapped to ActionScript ArrayCollections?

This chap nearly had it, but not quite:

Answer 1

After upgrading to CF 9.0.1 & BlazeDS 4, I finally have an answer to this.

You can now use the following node in you services-config.xml

<serialize-array-to-arraycollection>true</serialize-array-to-arraycollection>

Answer 2

For what it's worth, a ColdFusion Query object maps directly and automatically to an ArrayCollection. So if it's an option, you could manually create a query object and return that from your service.

i just stumbled on this article on serialization via java. I have yet to try this (hopefully later today). Hopefully it helps some.

Answer 4

From Java to Flex a List (Java) maps directly to an ArrayCollection (AS3).

You can see a full list here. http://livedocs.adobe.com/livecycle/es/sdkHelp/programmer/lcds/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=serialize_data_2.html
