269099 - Back button results in wrong dropdown selection

Status: RESOLVED DUPLICATE of bug 182157

(Core :: Layout: Form Controls, defect)

Description

[Bart Schouten]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 1.0.3705)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10.1

When you click the back button in a browser after you have made a selection in 
a dropdown box Mozilla will not select the correct index if more than 1 item in 
the dropdown have the same value.

Reproducible: Always
Steps to Reproduce:
Fill a <select> with 10 items, make sure that a couple of items have the same 
value but all must have different texts. Put an action on the form so that it 
submits to another page. Run the script, click an item. The other page is 
openened, and now click 'back'. If you for instance selected something with 
value 42 and the <select> has more items with this value, you'll notice that 
the -last- item with value 42 is selected now instead of the one you choose 
before.
Actual Results:  
Wrong index selected.

Expected Results:  
Right index selected ;)

Mozilla shouldn't try to determine the selected index itself by comparing 
values, but should (as IE does) remember the selected index and select that one 
again after a "back" button click.
