RE: [flexcoders] Sending complex data types to ColdFusion form Flex 1.5

Your custom ActionScript object is translated into a ColdFusion structure. So, make sure your object name and the argument name are identical, then make sure the argument type is struct.

When you pass custom objects back from the server, make sure they are arrays of structures.

Here is a call to the RO:

restService.addReview({review:event.eventReviewProp})

In the CFC:

Subject: [flexcoders] Sending complex data types to ColdFusion form Flex 1.5

Hi all,

I have been trying to use Remote-Object to pass complex data types from

Flex to ColdFusion - to no avail. Simple arrays and strings can be

passed easily, but as soon as I send an object all hell breaks loose.

I am running ColdFusion 7 (updater 3) on Win2K with Flex 1.5 (all on one

machine) using Apache 2.

If anyone has a working example on how to pass complex data types to

ColdFusion that shows how I can read them out as argument.passedinobject

I would greatly appreciate your help.

Here is the situation:

I am wrapping annotationdata into a shell object which is sent to a

ColdFusion component. Using the debugger, I can see that the correctly

formatted object is sent out. However, ColdFusion responds with "unknown

error" if I try to access the passed in data.

I don't get an error if I don't set a datatype or required to yes.

However, I am also unable to access the passed in object.

Thanks,

Kai
