My Inbox - No Master View

Hello Guys,

I'am facing a strange issue.

We have some Fiori tiles already productive and we want some more workflow's in our Inbox.

-> Means that all basic configurations are done

So I've added a new Workflow to a generic Tile and used the TASKPROCESSING Service to get the data from the backend.

The Items where counted correctly:

Also the Workitems are visible:

But there are no Details..nothing.

The only thing that the browser console say's is:

Uncaught TypeError: Cannot read property 'length' of null

This is the Version we have installed right now:

UIX01CA1 100 0005 SAPK-10005INUIX01CA1 UI for Cross-Applications

Do you have any ideas?

Thanks in advance!

Best Regards

Marvin
