We noticed the following phenomenon in an HTML Report only in the last 2 weeks (worked fine before that):

In a Checkbox value prompt with "Select UI" set to "Check box group" the check boxes next to the items are mostly not displayed when unchecked. When checked the box becomes visible.
This behavior is somewhat inconsistent: The list the last visible item in the list has the unchecked box displayed while for all the items above it the unchecked boxes are not displayed. When clicking to check the box, the checked boxes are displayed correctly.
When scrolling down in the list, the unchecked box does appear for every new at the bottom of the list that becomes visible during scrolling but then disappears as soon as the item moves up and a new item becomes visible at the bottom of the list.


This happens in both Chrome (Version 93.0.4577.63) and Edge (Version 93.0.961.38) in CA 11.1.7

Any ideas about the cause or the solution?

As both Edge and Chrome are both based on the same architecture, Chromium, I believe it's likely the latest version broke something.

I've opened a PMR, but I've been experimenting with possible fixes until IBM releases a hotfix. The first thing I've found is that increasing the size of the image from 16px to 18px does solve allow the checkbox to be visible. The big problem with that is that pixel-perfect reports may be affected by the increased size of the images. If I don't hear back from IBM in a few days I'll post a note about how to implement my fix.

That's strange. I had the same problem, but could not recreate it on current systems 11.1.7 FP3 as well as 11.1.2. Both systems were running on different operating systems...

Maybe a problem with certain operating systems or web servers?
What environment do you have in use?

additional info. The problem is still in the newest CA Versions. it also depends on the zoom factor.

Try to change the zoom factor 80% - checkboxes are missing:

Zoom Factor 90%:

Jens, thank you for this lead.
I moved the browser window between different displays (monitors) and also saw that the problem is connected to the zoom definition - in my case not of the browser window but of the display itself:
With a display resolution of 1920x1080 and a scaling of 100% the problem consists but with the same resolution and a scaling of 125% the problem is solved.

Until this is fixed, you can manually modify an internal Cognos CSS file to fix it.

In \analytics\webcontent\bi\pat\hal\hal.css and \analytics\webcontent\pat\hal\hal.css
Find and change the following:


to:



IMG.clsLVRadio,
IMG.clsLVRadio_checked,
IMG.clsLVRadio_checked_disabled,
IMG.clsLVRadio_disabled,
IMG.clsLVCheckbox,
IMG.clsLVCheckbox_checked,
IMG.clsLVCheckbox_checked_static,
IMG.clsLVCheckbox_static
{
height: 16px;
width: 16px;
/* This prevents the radio and checkbox images from shrinking when there isn't enough room */
min-width: 16px;
vertical-align: middle;
}

to

IMG.clsLVRadio,
IMG.clsLVRadio_checked,
IMG.clsLVRadio_checked_disabled,
IMG.clsLVRadio_disabled,
IMG.clsLVCheckbox,
IMG.clsLVCheckbox_checked,
IMG.clsLVCheckbox_checked_static,
IMG.clsLVCheckbox_static
{
height: 18px;
width: 18px;
/* This prevents the radio and checkbox images from shrinking when there isn't enough room */
min-width: 16px;
vertical-align: middle;
}


For some reason under 18px the checkboxes don't show up consistently. I believe this might be a bug introduced in the latest Chromium release, but this should fix it in the meantime.
