Ole and MC,
Just so you guys know, I tried this feature but it creates some problems. It could as well be a bug in soapUI ( don't know if all versions but TRUE with 2.5.1 )
Here is what happens:
In soapUI 2.5.1 Go to preferences -> WSDL Settings tab.
Turn on "pretty print project files" option.
Make some changes to project save project
try executing test cases or test suites. No SOAP Test Request works !! everything fails.
STRANGE BEHAVIOR IS:
In order to make sure everything works again, I had to restart my computer as plain reloading of older project or workspace did not work!
