re: [flexcoders] Find the value of a radiobutton in a radio group
I think I am finding that the problem is in the nextQuestionPlease() method.
The reference to questionsVS is null and I can't figure out why.
Here is the function:
public function nextQuestionPlease():void {
questionsVS.selectedIndex=currentQuestion;
}
Here is the viewStack:
mx:ViewStack id=questionsVS width=98% height=100% paddingLeft=10
questions:question1 /
questions:question2 /
questions:question3 /
questions:question4 /
/mx:ViewStack
In my init I set it to 0 and it appears how it should. How can I instantiate it?

Subject: [flexcoders] Find the value of a radiobutton in a radio group
I am trying to make a AIR app that is a test. I have radiobuttons with a value
of either 0 or 1 depending on if its correct or not. I want to pass the value
to a function that keeps score. I am running into a problem on determining the
value of the passed question to see if the app should add a 1 to the score or
not. I keep getting 'Error #1069: Property value not found on Number and there
is no default value.' when I click the button.
Here is my radiobuttongroup:
mx:Label fontWeight=bold text=1. Which layer(s) of the OSI Reference Model
provide(s) for internetwork connectivity? /
mx:RadioButtonGroup id=group1 /
mx:RadioButton paddingLeft=10 groupName=group1 label=Data Link
value=0 selected=true /
mx:RadioButton paddingLeft=10 groupName=group1 label=Physical
value=0 /
mx:RadioButton paddingLeft=10 groupName=group1 label=Session
value=0 /
mx:RadioButton paddingLeft=10 groupName=group1 label=Network
value=1 /
mx:RadioButton paddingLeft=10 groupName=group1 label=Presentation
value=0 /
mx:Button label=Next click=testMod.checkSingle(group1.selectedValue) /
Here is my function:
public function checkSingle(answer:Object):void {
if (answer.value !=0) {
Application.application.score += 1;
}
nextQuestionPlease();
}
How can I get it to find the value and determine if it should add 1 or not.
Thanks.
RE: [flexcoders] Find the value of a radiobutton in a radio group
It is my strong preference that anyone asking a question about an error post
the entire stacktrace. It is like a fingerprint and makes it much faster for
me and others to identify problems.
In the original post, you are using selectedValue as the parameter which will
be 0 or 1, not the radiobutton itself. The rb should be in the rbg's selection
property

RE: [flexcoders] Find the value of a radiobutton in a radio group
That part seems to work fine no that I went through the
debugging values. Its a null reference which ties to the questionsVS
viewstack.
Here is the error for that.
TypeError: Error #1009: Cannot access a property or method of a null object
reference.
