Status: RESOLVED INVALID

Note, URL was not given as user will need login, if QA engineer of Mozilla 
would like a login i can give one privately if they would like to contact me, 
but would rather not have everyone able to login.

=====================================================

I'm using 1 frameset containing 3 frames.

frame 1 has a javascript function when i click a link that updates the other 2 
frames:

function updateframes()
{
parent.thelisttop.location.reload()
parent.thelistbottom.location.reload()
}

thelisttop is top frame and thelistbottom is bottom frame, both of these 
frames contain a javascript timeout for refresh like this:

function update()
{
setTimeout("location.reload()",<?php echo $refreshrate2[refresh];?>*1000)
}

The php echo gives the output of 10 in this case.

When the page is loaded first time all the frames are fine and the content of 
each frame is correct. 
When i click Reload in the mozilla browser, the frameset reloads as expected 
but often only 2 frames load, either of the top and bottom will fail to load 
and appear that the frame doesn't exist (though in the frameset it's there, 
but if you right click on the frame there is no "This Frame >", but sometimes 
both frames will load correctly.

I am told (and thought myself) that this could be related to both the manural 
reload and the separate frame reload trying to take place at the same time. 
Which i asked a friend about who responded with:

> i'll have a look at the inside of mozilla (source)
> it says there is an uncaught exception
> onreload
> i think it's the problem of dueling "refreshers"
> congratulations you've just discovered a bug
> post it to bugzilla
> it seems if you hit the refresh-button and a script tries to refresh...

The problem doesn't give any errors when i reload any of the frames 
individually but only when i do a manual reload of mozilla.

This problem doesn't occur in Internet Explorer but does happen in Netscape 
(same gecko engine as Mozilla)



In the meantime i need a workaround:
------------------------------------
At the moment it seems my only solution is to re-design the whole lot and use 
<div> with auto scroll and include what would be within the frames in those, 
can anyone think of any other solution i might be able to use. Meta refresh 
didn't seem to be stable either as when i clicked a link from the page with 
the meta refresh, the page would not continue it's refresh timer and the only 
reason i can see this being is because it lost the focus() but not sure, 
doesn't work in the frames though.

Reproducible: Sometimes

Steps to Reproduce:
1. Open URL
2. Login
3. When redirected to next page, 3 frames appear, allow them to refresh if you 
like
4. Click Reload in Mozilla menu at top, sometimes top of bottom frame will 
hold no content and be as if it does not exist.

Actual Results:  
Intermitent problem as mentioned above

Expected Results:  
Reloaded the frameset and frames should all load in full with content and all.

got an error when i selected something from the select box named 'component' 
id 'component' even on this bug submition page.. maybe someone made an error :P


248 'null' is null or not an object.

Reporter: does this still happens using a current build?
Can you attach a testcase, so that people don't need to login to that site to
test this?

Kann ich bestätigen. Javachat mit Frames und das Chatframe wird seit Firefox 35.0.1 nicht mehr geladen.
