There are two aspects to this: 1) the ASP application should not throw a tantrum when it does not receive exactly the input it is expecting; it should generate a sensible error message.
2) Fixing the JMeter test plan to generate the appropriate viewstate. If you can establish exactly how your particular browser generates the viewstate, then it should be possible to use JMeter to generate it. This may require additional code, or it may be possible using the existing facilities. I don't have time to do the investigation, and I don't have any application I can test against. But if you can provide the information, I can check if it can be done in JMeter already, and perhaps add any necessary code. S.
