If you plan upgrading built-in LCDS to version 2.6 you should follow the instructions provided in the LCDS_for_CF.txt under the resources/ColdFusion folder.

Additionally to that, you should also copy the cfgatewayadapter.jar that you can find under the { extractedLCDSFolder }/WEB-INF/lib to your ColdFusion /WEB-INF/flex/jars folder.

In my previous post, I mentioned that Flex 3 revision 1092 should be used but unfortunately there is a bug which creates a lot of stacktraces on your server's logs and it seems that it has been fixed in revision 1122 that you can get here.

throwing that the returned type of the init method wasn't of the type 'coldspring.beans.DefaultXMLBeanFactory'. This is weird because my Application.cfc is in my webroot, the ColdSpring folder also and I have a / for the webroot (needed for RTMP).

I was working on a LCDS project with Flex Builder when I realized that code-hinting was providing me information for arguments regarding the commit method on the DataService class.

If you take a look here you'll see that commit method isn't expecting any argument. The 2 arguments Flex Builder was listing was ItemsOrCollections and cascadeCommit.
