148827 - iframe content doesn't always load

Status: RESOLVED WORKSFORME

(Core :: Layout: Images, Video, and HTML Frames, defect, P3)

Description

[Kevin Cook]

When visiting the sample URL, the content of the page's <iframe> often doesn't
load.  Page reloads via the F5 key don't always make the content appear either.
 Usually, however, by right-clicking in the blank frame and doing a frame
reload, I can make the content appear.

Happens also with Mozilla 1.0.0+ , Build ID 2002060221, Linux.

 WFM with branch build 20020603 7.0b1 on Linux an WIN2K.

Confirmed.  Additionally, loading the page on its own does not have trouble, so
this is likely frame src stuff.

Attachment: testcase (iframe.zip)

I see a similar problem, using Moz1.1a (2002061104)
This test case contains a simple use of IFRAMEs, 
and has a number of 'peculiar' behaviours.

NORMAL BEHAVIOUR:
1) open main.html
   by default, iframe1 is loaded
2) click on '1', then on the 'click' button -> 'hello from iframe' in textarea
3) click on '2', then on the 'click' button -> empty textarea

OBSERVED BEHAVIOUR:

1) press 'enter' again in the address bar or press 'reload'
sometimes the IFRAME does not display

from the server logs, I can see the IFRAME is loaded
clicking the 'click' button copies text from inside the IFRAME,
and it's there alright 

2) SHIFT+reload sometimes renders the content of the IFRAME TWICE !!!

3) results vary if the pages are local, on a webserver, or on an appserver 
(these files were jsp, but I saved them as html)
so this may be a timing/caching issue, 

4) changing the 'preferences->advanced->cache->(radiobuttons)' settings has
some influence.

forgot one... 
5) browsing menus (without clicking any menu entries) can cause the iframe to be
displayed:
sometimes opening menu "file" and hovering the mouse over the entries, then
switch hovering to menu "edit", especially opening the submenu "view->Use
Style", then the IFRAME is suddenly rendered (but not requested, it was there
already!)

I have found a similar problem. See attachment 89695 [details].
While the alert is present, loading works fine. If you remove the alert, the
iframe is not loaded.

Also, I have found that the iframe has the properties
document.getElementById("i1").src and
document.getElementById("i1").contentWindow.location and these are often
different. How can that be?

I am not sure if I did this right, but things seemed to WFM fine.  I loaded the
given URL a few times, and everytime the IFRAME loaded (although sometimes it
took a moment longer to load up).  In the first testcase, I observed the 
"normal behavior" but did not observe the problem (1) listed in the "observed
behavior".  In the second testcase, I removed the alert and the IFRAME still
always loaded up as it should.

Can the authors verify whether or not the problem still occurs?

Comment 9

[Kevin Cook]

The good news is that I haven't seen this behaviour in a while either.  So you
might as well close out this bug :)
