231431 - Get JS error on using radiogroup's checkAdjacentElement method if no element has the focus

Status: RESOLVED EXPIRED

(Core :: XUL, defect)

Description

[m.d.nauta]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7a) Gecko/20031225

I have a XUL page which contains among others a radiogroup. If I call the
checkAdjacentElement method of this radiogroup while focus is at another
element, I get a children[i] has no properties error in the JS console. The
reason is that i gets 1 too big. Line 153 in
mozilla/xpfe/global/resources/content/bindings/radio.xml should read:
for (i=0; i<children.length-1; ++i) { instead of 
for (i=0; i<children.length; ++i_) { what it is now. If I am correct a call to
this method with this tiny improvement will result in the first radio element
being focused of focus is not on one of the radio-elements in the radiogroup.

Reproducible: Always

Steps to Reproduce:
1.
2.
3.

Actual Results:  
JS console reports a children[i] has no properties error 

Expected Results:  
Select the first radio element in the radiogroup.
