Hi!
Trying to resolve problems with custom timeouts I try to migrate my tests to newer Gatling versions.
With M3 I receive huge amount of errors, so I try Gatling2.0-M2.
But during the test, all requests, where I use check by xpath ended with same type error:

I recheck my page xpath structure – It look ok. Also the same tests with Gatling2.0-M1 going ok.
