Bug with default RadioChoice "for" attribute on label generation.
-----------------------------------------------------------------
Key: WICKET-1797
URL: https://issues.apache.org/jira/browse/WICKET-1797
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4-M1
Reporter: Ned Collyer
Priority: Minor
If you use 2 forms of the same name, with radio choice with the same name and
values, then the "for" attribute is generated based on the name relative to the
current form, and the index of the option.
This generated incorrect html.
The behaviour is: when you click on the label of radio items in the second
form, the items in the first form are selected.
For example
class userdetailspanel extends panel {
userdetailspanel(string id) {
super(id)
Form form = new Form("testForm");
List SITES = Arrays.asList(new String[] { "The Server Side", "Java Lobby"
});
form.add(new RadioChoice("site", SITES));
}
}
class detailspage extends page {
detailspage() {
add(new userdetailspanel("panel1"));
add(new userdetailspanel("panel2"));
}
}
This is because of the way the IDs are generated in RadioChoice. Specifically
around
String id = getChoiceRenderer().getIdValue(choice, index);
final String idAttr = getInputName() + "_" + id;
A workaround I have has been adding a choice renderer when creating any of
these RadioChoices. I have been overriding getIdValue to return something
unique. (based off the housing components markupid)
