Hi, I went through page 7-8 of following link
Difference between my project and tutorial is I have instead if Date field another RadioButtonGroupedByKey. Anyway, I did the actions, parameters, key mapping, and code and after no errors deploying when I press "Not Married" field is not going red like on the picture but I get
com.sap.tc.webdynpro.services.exceptions.WDIllegalArgumentException: Parameter Key not found
When I press "Married Since" same error appears. So, it's clear there's some "Key" problem, mapping whatsoever is not clear for me, anyway I think I did all that those two pages of tutorial said and cant find mistake on my own. Please, any advice will be most welcome. Johnny.
