a4j:support strange events
I'm using a selectOneRadio to modify a selectOneMenu and it almost works correctly except for some inconsistent behavior.
I'm passing a paramter in the querystring and sometimes
when I click the radio button the value will remain the same as the passed in value. For instance if I pass in a '3' when I click on the radio button whose value is '1', I'll get '3'. If I click again, then it turns to '1'. It seems like it's storing the initial value along with it's real value.
Also, if some unrelated fields are empty the radio button value will not change when clicked. When I enter text in that unrelated field the value will change.
Are these bugs or am I doing something wrong?
