Description Ian Springer 2011-07-12 18:30:44 UTC 
To reproduce this. go to a Resources list/search view (e.g. #Inventory/Resources/Services) that contains more than one pageful of Resources. Scroll down past the first page of data and quickly hover over an ancestry column (Name or Ancestry) before its data has been loaded (i.e. while the list grid still says "Loading data..."). You should see the error.

Here's the js stack trace:

Comment 1 Ian Springer 2011-10-11 20:39:18 UTC 
[master e8e21d0] (http://git.fedorahosted.org/git/?p=rhq/rhq.git;a=commitdiff;h=e8e21d0) fixes this. Now if you try to hover over an Ancestry or Name cell before the grid data has loaded, no NPE will occur and no tooltip will be displayed.
Comment 2 Ian Springer 2011-10-11 21:26:27 UTC 
[master c48d39f] (http://git.fedorahosted.org/git?p=rhq/rhq.git;a=commitdiff;h=c48d39f) fixes a 2nd instance of the same kind of NPE.
Comment 3 Sunil Kondkar 2011-10-13 08:57:31 UTC 
Verified on build#523 (Version: 4.1.0-SNAPSHOT Build Number: 91b72c2)

Navigated to 'Inventory/Resources/Services'. Scrolled down and quickly hovered over Name and Ancestry columns before its data has been loaded, no exception is observed.
