Using Form and specifying XSI type results in huge request

Hi,

In your vmoptions file change xms to 128 instead of 512.
I am able to create a new request from the operation in 4.6 and there will be a pop-up asking if I want to include optional elements or not (when the option is not set in Preferences/WSDL Settings). That works if I say no to including optional elements.
And when the option is set in preferences, that's when it creates the request with all the optional elements without prompting to confirm any option. I tried this on 4.6 and it worked. I suggest you backup your project and download our latest release which is version 5.1.2 maintenance build: http://www.soapui.org/Downloads/soapui- ... uilds.html
Let me know if the option works for you.

Thanks,
Jeshtha
