Version: 2019-09 (4.13)

Ubuntu 18.04 and 19.10 and Linux Mint 19.3

1. Create and display a TreeViewer with TextCellEditor support unpopulated with no tree nodes.
2. Populate the TreeViewer with a model by calling TreeViewer#setInput(model)
3. Attempt to edit a tree node by clicking on it. The TextCellEditor does not appear.

2. Attempt to edit a tree node by clicking on it. The TextCellEditor does appear

Attached is a Snippet to reproduce this. Note this is a Linux only bug.

Run the snippet.

1. You will see two buttons and a space where there is an unpopulated Tree.
2. Press the first button. The tree is now populated.
3. Try to edit a tree node by clicking on it. The TextCellEditor does not appear.
4. Press the second button. A new tree is created, populated with a model and tree nodes.
5. You can now edit a tree node by clicking on it.

You probably found bug 550606. Had you tried current Eclipse version 2020-03 (4.15)? (4.14 should be fixed as well)

Yes, thanks. I tried with 4.15 and it's working OK.

Sorry for the noise, I searched for it first before reporting but didn't find anything.
