Hi!
We have some Problems with our RAP GUI and IE 7 running in with ssl
communication:
The first Problem is, that the browser prompts a dialog with the message,
that our site has secure and unsecure items that istn't true.
The second and even bigger problem is, that their are some icons (PNG
format) that don't display. Very strange is the fact, that one of the icons
on a button is visible if the button is disabled and the icon is grey, but
if the button is enabled and the icon would be in color, the icon got lost!
Switching to normal unsecure communication by http protocol, all icons are
visible.
Any ideas?
Thanks for reading and thinking about it!
Alois

I don't have exactly a clue what might cause your problem. But if your
browser complains about unsecure items, maybe those missing images
somehow refer to wrong (http) URLs? Do you have any URL rewrites or
aliases in place? Could you try to track the requests? Just an idea...
Best regards, Ralf

Hi Ralf,
We already tracked our http request: We have only relative url and some of
the icons in the same folder were shown in ssl and some others not. Perhaps
this has something to do with a IE 7 Bug I found in the qooxdoo bug databse:
http://bugzilla.qooxdoo.org/show_bug.cgi?id=1021
But it's still strange that this behaviour doesnt apply to all icons.
Thanks,
Alois

Interesting, I wasn't aware of this bug. It refers to two other bugs
#890 (Mixed content warning) and #710 (IE+SSL+PNG). Both have been
resolved fixed lately, so I'm afraid we can't fix this issue before the
adoption of qx 0.8. Would you mind to file a bug against RAP? That would
allow you to stay tuned.

In the latter of the two bugs it is stated that this issue is related to
a workaround for the transparent PNG problem in IE. So maybe PNGs
without an alpha layer are not affected?

Hi Ralf!
After hours of debuging and request tracking we did some simple experiments:
It was very strange, that the internet explorer displaye all icons in http
but not all in https. So first of all we tried a servlet filter to change
the url of the png to it's complete path -> nothing changed. After changing
the protocol from https to http in the url (-> displaying mixed content) the
png were visible. We also tried jpegs - they worked with both protocols. So
i changed the suffix of the png to jpg (I don't know why!) - now it works,
the png-icons were visible!
This seems to be an ugly bug of IE!
Best regards,
Alois
