some components will not display data tag.
The viewer (java app, run on my windows PC) will not display the data tag (device name) in the status bar for some components, even when it will do it for that component type in general.
E.g. HINS/waterflow.xml the two leftmost switches inside the green outline box will not display their tags, but
other switches will. Attached to H:M1DC9 and H:LDFSWL. (You also can't right-click to copy the device name.)
Spinner component types and input fields do not display any data tag info even though they could (they have inputs) (e.g. NML/CM1/ilock_bd_multi3.xml)
When a file is used as an embedded display, you also lose the displaying of the datatags from the embedded display. (e.g. NML/CM1/ilock_bd_multi3.xml in NML/CM1/ilock_cm1.xml) (the bit-arrays data tags show up when not used in embedded mode).
