58616 - Dataloss when updating TEXTAREA value when display:none is set

Status: RESOLVED DUPLICATE of bug 57269

(Core :: Layout: Form Controls, defect, P3)

Description

[djoham]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.14-15mdk i686; en-US; m18) Gecko/20001030
BuildID:    20001030

If you update the value of a textarea when it's wrapped in a div with display:
none set, the new value will be lost when the DIV is made visible again


Reproducible: Always
Steps to Reproduce:
Open test case I'll submit. Follow instructions	

Actual Results:  the value the textarea had before it was made invisible is
returned when it is made visible again, even if that value has changed via javascript.	


Expected Results:  the   textarea should retain the value I give it, no matter
what happens to it.

IE renders as I would expect
Textboxes render as I would expect (even in mozilla).


This bug causes dataloss since updates to hidden textareas are lost when that
textarea is made visible again.

This bug is critical for the above reason and since the workaround (saving
values and resetting them after the textarea is unhidden) is really hokey and
very prone to error. Plus it makes us look silly

Changing to HTML Form Controls and confirming.  The textarea's value is part of
the DOM, so it should be stored in the DOM (not the frames).  That's what having
a DOM implementation means, right?
