13485 - [LAYER] Contents of NOLAYER are not displayed.

Status: VERIFIED FIXED

(Tech Evangelism Graveyard :: English US, defect, P2)

Description

[Dritan Suljoti]

It seems like the new browser does not support the layer/ilayer tags.

However content that is wrapped inside <nolayer> tags is not shown either. Should't this be eliminated. The content within the nolayer tag should be displayed in this case.

Per our conversation earlier, Nav5 will ignore the LAYER/ILAYER tags but display
their contents (if any) as well as the contents of any NOLAYER tag.  Troy, if
you haven't filed a bug against yourself already to make that parser change to
pass through contents of NOLAYER, you can use this.

Comment 3

[troy]

Why would I be making parser changes?

Rick, are you going to be making this change?

Harish -- one for you.

It is urgent that we fix this bug ASAP (probably immediately post-dogfood)
because: (1) we are asking external content/web app developers to modify their
content to support Nav5, and (2) those who use <LAYER
...><NOLAYER>...</NOLAYER></LAYER> markup as a cross-browser support technique
are blocked on doing their upgrades until we fix this.  We don't want to block
the people who are trying to support us. ;->

On further investigation, I think this bug is INVALID. Open
http://sites.netscape.net/ekrock/tests/layer-then-nolayer.html in Mozilla.
(I used 1999113012 of Commercial on WinNT 4.0 SP3.) Contents of NOLAYER *are*
displayed in Mozilla as expected.

OK, there seems to be a problem here.  Before, I was unable to contact the
server for the original page http://www.demoserver.com/drit/think.html. Now when
I display it and view source, it appears that there *is* content that we'd
expect to be displayed:

<IFRAME SRC="http://ad.doubleclick.net/adi/drit.support.net/;thnk=unum3"
MARGINWIDTH=0 MARGINHEIGH=0 WIDTH=468 HEIGHT=60 HSPACE=0 VSPACE=0 FRAMEBORDER=0

</iframe>
</nolayer>

... but we're not seeing it.  In fact, I see practically nothing for this page
on either Nav4.7 or 11/30 Nav5 Commercial.

There appears to be a problem, but it's nothing so simple as contents of NOLAYER
failing to display in all cases.  I've attached a test case showing that Nav5
*does* display the contents of an isolated NOLAYER. It's online here:
http://sites.netscape.net/ekrock/tests/layer-then-nolayer.html

dsuljoti, could you please try to create a simplified test case with the minimal
HTML markup and images necessary to reproduce the bug?

For a whole matrix of LAYER, ILAYER, NOLAYER, and IFRAME combinatorial test
cases, see http://sites.netscape.net/ekrock/tests/matrix.html

Good news: I spoke by phone with dsuljoti. By comparing the behavior of M11 and
11/30 Commercial, we found that this bug occurred in M11 but no longer occurs in
11/30 Commercial.  Clearly, it was fixed between M11 and 11/30, so I'm closing
this bug out as INVALID.  Thanks to all!

Marking Verified.

Comment 13

[ekrock's old account (dead)]

Moving all [LAYER] bugs to Evangelism component for tracking and open-source
evangelism by mozilla community members of sites that need to upgrade to support 
web standards such as HTML 4.0 (instead of LAYER/ILAYER) and the W3C DOM
(instead of Nav4 document.layers[] or IE document.all()). Sites should be
lobbied to do the upgrade using the email templates that are linked to from
http://www.mozilla.org/newlayout/bugathon.html#layerbugs . When a site's owner
has confirmed receipt of the message requesting an upgrade, the bug should be
marked with the keyword evangelized to indicate that evangelism for that bug is
complete. When the site finishes the upgrade and supports standards, the bug
should be closed.

Comment 14

[ekrock's old account (dead)]

Closing all Evangelism bugs where no evangelism is needed because page has been 
fixed, site is internal to Netscape, report is a DUP, or bug report is no longer 
appropriate for evangelism for any other reason.
