2 different RadioButtons (completely free to eachother ) behave like connected to each other
Hello guys,
I have a weird problem in my project , basicly speaking , I created a
widget called readingQuestionsWidget , it has UI to show the reading
questions for my exam project , in its controller class i fetch
reading questions from my database ( a question has a reading text and
4 different options below the text, so i prepared 4 radio buttons for
the options.) , for all different reading questions i put a READING
WIDGET which i created, for example , if there are 2 reading questions
i put 2 different READING WIDGETs(which they have 2 different text
boxes for the reading texts and 8 different radio buttons ( each 4
belongs to a reading text) ) on my page.
While i want to control the answers (which i check a radio button) ,
for example , the radio button for the option "A)" of two different
questions behave like connected to each other. I mean , when i check
the A) option for the 2 different questions , the first one that i
checked behave like NOT CHECKED.
here are my classes;
