Description of problem:
When a specific item is selected in the left-pane tree, and a user tries to edit that item, the name is disabled for editing because the item is currently selected. This is the correct behavior. However, there should also be a message printed to the user that explains *why* the name cannot be edited.

There is code in the application to show a message, but it is not working.

Example:
In HostListModel.java
innerHostModel.getName().setInfo("Cannot edit Host's Name in this tree context"); //$NON-NLS-1$

At current count there are about 20 of these in uicommonweb. I don't see any evidence that the application uses these messages.

How reproducible:
Always

Steps to Reproduce:
1. Select an actual host in the tree.
2. Click edit.
3. You cannot edit the host name. There is no help to tell you why.

Actual results:
There is no help to tell you why you cannot edit the name.

Expected results:
There should be a message shown that says something like "Cannot edit Host's Name in this tree context"
