Bug: Inconsistent behaviour of Pasting in the Explore pane

[rleigh]

The copy and cut icons are greyed out when unavailable. However, the paste icon remains active even when pasting is not possible:

1. Select image file and copy.
2. Paste into different container types:
   • Dataset (succeeds, unless it's already in the container)
   • Project (fails silently, does nothing)
   • Screen (fails silently, does nothing)
   • Plate (fails with "Destination not supported" error)

3. Select dataset and copy
4. Paste into different container types:
   • Dataset (copies dataset /contents/, not error as expected)
   • Project (succeeds, unless duplicate)
   • Screen (fails silently, does nothing)
   • Plate (fails with "Destination not supported" error)

5. Select screen and copy
   • Does not support copying. Why can't I copy/move a screen into a Project?

6. Select plate and copy
7. Paste into different container types:
   • Dataset (fails silently)
   • Project (fails silently)
   • Screen (succeeds, fails if duplicate)
   • Plate (fails with error "Cannot move plate to plate")

So to summarise:
Failure is handled inconsistently, both by

• allowing paste where it will definitely fail
• allowing paste even when the icon is greyed out (it's still functional, or apparently functional), and the greying is sometimes inconsistent even for the same container type
• not producing errors in all cases where a failure to paste occurs

The behaviour should be consistent, understandable and give feedback to the user rather than silently failing.

Roger

Only allow paste on compatible types ​https://github.com/will-moore/openmicroscopy/commit/869972bd6c20f8ac837255c1b8ccf88ac40ae94d

(In [869972bd6c20f8ac837255c1b8ccf88ac40ae94d/ome.git] on branch develop) Only enable 'paste' if jsTree nodes are compatible. See #8778
