Hi there
I've just spent 2 hours trying to figure out what was causing my problem.
I have a web service which in some cases could throw an exception. When using the RadCompression module, the exception is not properly deserialized by the MS Ajax framework, resulting in a "'Message' is null or not an object" JavaScript error.
How can I properly receive exceptions from my web services using the RadCompression module?

Hi Kenneth,
I'm afraid that little can be done in this case as the compression filter is already applied to the response stream at the point where exception has been thrown. Thus you may consider to disable the compression for the pages which use the webservice in question. Or you may subclass the compression module and overriding the IsHttpCompressionEnabled to skip the json content type.

I understand that the compression is already applied, but why can't the Ajax framework decompress an exception? I'm not interested in completely deactivating compression of JSON content, I just wan't to be able to catch the exceptions on the client side.
Is it a bug in MS Ajax?

Hi Kenneth,
It seems that the error is caused by the fact that when the exception is thrown on the server the response's content encoding header is removed by the ajax framework and the browser is not aware that the content should be decompressed. However I'm happy to inform you that our developers has managed to find a possible workaround for this case, thus we will do our best to incorporate it in the next internal build of the module.
