- given:
	- I go to the report builder/branch analysis
- I select a process definition
- I open the flow node filter modal
 
- when:
	- I select a flow node without a name
 
- then:
	- an empty flow node key is shown in the preview  (see error-in-flownodefilter-preview.png ) )
- if I add the filter the empty key is also shown in the control panel
 
- an empty flow node key is shown in the preview  (see error-in-flownodefilter-preview.png
- expected:
	- if the flow node name is not available, I can see the flow node id instead in the preview and in the control panel as well
