Why ServiceNow don't refresh Tabs from my Dashboard

[Manuel W_]

Dear Community, 

I created a Dashboard with 4 Tabs and reproduce the issue with another dashboard with 2 Tabs. 

Same problem, so when I want to switch the different tabs chrome and microsoft edge dont refresh the page by themself, I need to refresh the page manually by hitting F5.

Do you have heared about that bug?

Best regards.

So with that, there may be something else going on.  I would put in a Case with HI to see if there is an underlying issue going on.

Hi I do not think this is a bug. I think this is the expected behavior. Let me know if that answered your question and mark my answer as correct and helpful BR Dirk

Dear Community, 

I want to share my solution with you. There ist a bug in service now which is written down here

https://hi.service-now.com/kb_view.do?sysparm_article=KB0752512

Description

"From the customer perspective, this issue is presented on Responsive Dashboards that contains more than one tab, and the content of these tabs have one or more reports. Clicking on a few of the tabs does not work, and the content of the dashboard remains the same. This is not the same as having several tabs with the same content because the content itself does not refresh when the user clicks on the tab.

From the technical support perspective, when we click on the tabs that don't render content on the dashboard, what we see by using the console log from the browser's dev tools is malformed JSON."

Release or Environment

All Releases.

Cause

The cause for this issue is that on the [pa_widgets] or [sys_report] tables, there are one or more records with "name" or "description" or "title" containing a special character. Also using copy and paste to populate the description filed can also copy special characters, thus causing the issue. it is preferable to manually type the entries. 

 

Resolution

Look at each of the widgets that are on your Responsive Dashboard, and check the name, title and descriptions fo the widgets. If you identify any non-ASCII delete and retype the text.

If you are still experiencing an issue, please open a case, and work with your Technical Support Analyst to provide you with a list of records that contain non-ASCII characters. You will then need to go through the list and remove and retype the text.

Means: You need to remove all "German ÄÖÜ.
