As is the custom, Chuck is right here. Since queryMatch is of type
NSMutableDictionary, it doesn't have a field named agent_person that
the compiler can decode. Enter key-value coding, the typecasting
nightmare, but quick and dirty coding dream.
agentDisplayGroup.queryMatch.takeValueForKeyPath("Agent Name",
"agent_person.surname"); should do the trick. If there is still an
error with your key path, you will get a run time error.

Hello;
The code was created by Web objects by using Add | New File from
the popup (right click menu) then selecting new display group
component. I have tried to access agentDisplayGroup from within
constructor, appendtoresult, an custom public functions.

"Cannot resolve symbol" is a compiler error. It means that you
typed something wrong. In this case, the wrong thing is
this.agentDisplayGroup.queryMatch
queryMatch is a method (or function) that returns a
NSMutableDictionary value, not an instance variable. As such, you
refer to it as
this.agentDisplayGroup.queryMatch()
That will leave you with another error at .agent_person as this is
not an instance variable (or a method) on NSMutableDictionary.
Beyond that I am not sure if you want to update
agentDisplayGroup.queryMatch(), or call setQualifier(), or
something else entirely. But it does look like you are doing more
work that what should be needed.

this.agentDisplayGroup.queryMatch.agent_weapons.serial =
"Serial"; // results in cannot resolve symbol
super.appendToResponse(response,context);
WXDebug.println(25,"**appendToResponse(): Done");
}
}

Don,
Hi. Can you share some of the code? Normally there would be no
reason you shouldn't be able to access it.
