That does fix part of the problem. Initially the radio buttons weren't actually in concert - the code in the Seaside book wasn't producing 'name="something"' code. I wonder whether that code would ever work?
Anyway, unfortunately, the callbacks are still not working. It is very odd. The form renders properly, it is just that the callbacks never fire. The code below shows two version - radio button and select statement. The select version works perfectly. I would be really interested to know how to go about debugging this.
renderContentOn:html
html form:
[
html radioGroup: [ :rg |
rg radioButton
selected: self contact isMale;
callback: [self contact beMale];
with: [html text:'male'].
rg radioButton
selected: self contact isFemale;
callback: [self contact beFemale];
with: [html text:'female'].
].
html select
list: #(#Male #Female);
selected: self contact gender;
callback: [:value| (value=#Male) ifTrue:[self contact beMale] ifFalse:[self contact beFemale]].
html submitButton on: #save of:self.
]
