Thanks for the quick reply. Unfortunately, I'm still getting the same
NullPointerException. I'm using the latest webtest build in maven format
(R_1440) which uses groovy-all-1.0-jsr-06. All of my other test cases which
store properties run successfully written in the format:
storeHeader(name: 'cookie', property: 'cookieHeader')
Anything else I should try?
Thanks,
Lars
