I tried it with 1.6.0_12. I still have the same behaviour. I get a empty page. I start now the MockService. The soapui-errors.log file is empty and the normal log file does not have any errors.
Inside the console i still see a IllegalArgument and a NullPointer Excpetion as mentioned in messages before.
System-ID unbekannt; Zeilennummer831; Spaltennummer84; java.lang.IllegalArgumentException: argument type mismatch
System-ID unbekannt; Zeilennummer831; Spaltennummer84; java.lang.NullPointerException
The numbers you can see is always the same. When i run my project or the sample project.
Where comes this numbers?
