Event Validation for Log in

Hello,

Excuse the possible stupid question, however I do not know what to do to get event validation working for a login request I'm doing. I sent a get to the page to retrieve the cookie and relevent page information, then send in a rest post for the log in. It works perfectly if I disable "enableEventValidation" however with it on, I guess it does what its supposed to. and throws :

Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page

Does anyone know how to get SoapUI 5.2.0 to send in / calculate the view state, or how to calculate and send within SoapUI.

Whats fustrating is i have the Rest requests all working, its just this one stage thats being a pain!

Cheers for the help.
