Can you use alternative as3commons-lang version with Spring AS?

[Dilbert]

Forgive me if this is a silly question, as I am relatively new to Flex and ActionScript. Our project is using Spring AS v1.1 and Cairngorm v2.2.1. We wanted to upgrade from as3commons-lang v0.3 to v0.3.5. However as soon as we do, our application no longer initializes. We get an error:

The property 'service' on the definition of 'oneOfOurBusinessDelegateFactory' could not be resolved. Original error: Error #2091

Below is the additional details from our logs. Rolling back to as3commons-lang v0.3 resolves the problem. We are building use maven & flex-mojos. We are excluding the as3commons-lanf from the spring dependency definitions and then setting them directly with the newer versions.

Is it not possible to upgrade to a newer version of as3commons lang? Or are we doing something wrong?

I see your original eror is 'Error: #2091'. When I look up the error I find this:

'2091 The Proxy class does not implement hasProperty. It must be overridden by a subclass.'

That might explain the problem actually, I'll try and look into this when I find the time. For now, unfortunately, all I can do is recommend you downgrade to version 0.3 for the moment.

Ok, I think I've managed to fix this.
If you upgrade to version 0.3.6-SNAPSHOT of as3commons-lang you should no longer encounter this error.

Cheers,

Roland,

Thanks for the prompt answers on the forum and for the amazingly quick fix in the code base. Very much appreciated.
