Recently we ran into an unexpected behaviour whilst testing Internet Explorer 11: after the user logs into the BPM Workspace loads, the application fetches instances in the background while a "Fetching data..." message appears. As soon as the data is about to the displayed, the whole page is re-loaded - and this keeps happening over and over again.
After testing for a while we discovered that the issue was actually related to the table itself. Once the data is sent back from the server to the client, the table is resized which (for some reason) triggers a window.resize event that makes IE reload the page.
The solution? As simple as changing the contentDelivery mode of the table to immediate. This actually works for us because we are using our own workspace application with the worklist component - but the issue keeps happening in OOTB components such as the default BPM workspace.
If you are using your own custom workspace then to make this change you would need to use MDS seeded customisations. Andrejus BaranovskisBaranovskis' has several posts on the subject.
Until next time!
