When I load the gwt files into Neoload I get the error: GWT ErrorMessage caught : Cannot deserialize field: protected. I think the only way to solve this is to edit the software code. This is not possible on the moment. In Neoload, most of the requests are translated well from GWT. Is it possible to NOT translate the request where it is going wrong? So all the requests are translated from GWT except one.
No you cannot ignore one GWT request. Either all the requests are decoded or you could record your script without the GWT module but in that case you may not be able to replay your script at all or it may be difficult to handle the dynamic values.
