Description Sakthivel Gopal 2002-01-11 20:23:58 UTC 
Have the Properties dialog open from View -> Properties.
Make a Database connection, the properties dialog shows properties for the
connection.
Right click on the connection & delete the connection.
Properties dialog is not reset & properties for the deleted connection are still
shown.
Click on any of these properties, it throws NPE

Comment 1 Radko Najman 2002-03-14 10:26:34 UTC 
This happened only if the connection node is "connected". If the
connection to the database is closed and the delete action is called
after it the properties window is reset.

Delete action should be enabled on "disconnected" node only.
Comment 2 Radko Najman 2002-03-21 11:21:39 UTC 
Fixed. Delete action is now enabled on "disconnected" node only.

In the future it should be enabled on "connected" node too and user
should be ask if s/he wants to close the connection before the delete
action. If not, the connection node will not be deleted. To delete
"connected" connection node without disconectiong isn't much clear.
(Will be investigated for new database module based on MDR)
Comment 3 David Kaspar 2002-11-18 15:11:44 UTC 
Verified in main trunk
Comment 4 Quality Engineering 2003-06-30 17:17:38 UTC 
Resolved for 3.3.x or earlier, no new info since then -> closing.
