Description John Sanda 2012-01-09 11:28:12 EST
Description of problem:
In the feature/gwt-upgrade branch, when I go to the discovery queue and click on the check box of child resource (i.e., leaf node), I get a globally uncaught exception in the UI. This happens when only when I expand the platform node without selecting it and then selecting one of the child nodes. This does not happen in the master branch.

Version-Release number of selected component (if applicable):

The exception I see when running in GWT dev mode is,

Caused by: java.lang.ClassCastException: com.smartgwt.client.widgets.grid.ListGridRecord cannot be cast to com.smartgwt.client.widgets.tree.TreeNode 	at org.rhq.enterprise.gui.coregui.client.inventory.resource.discovery.ResourceAutodiscoveryView.updateButtonEnablement(ResourceAutodiscoveryView.java:412) 	at org.rhq.enterprise.gui.coregui.client.inventory.resource.discovery.ResourceAutodiscoveryView.access$3(ResourceAutodiscoveryView.java:391) 	at org.rhq.enterprise.gui.coregui.client.inventory.resource.discovery.ResourceAutodiscoveryView$3.onSelectionChanged(ResourceAutodiscoveryView.java:264)

It appears that this might be due to usage of what is now a deprecated API in ResourceAutoDiscoveryView.

I have come across a couple SmartGWT forum posts that lead me to believe that this issue could be a regresssion in SmartGWT itself that was introduced in version 2.5. The aforementioned posts are,

Made change to avoid casting ListGridRecord to TreeNode in feature/gwt-upgrade branch.

Bulk closing of issues that were VERIFIED, had no target release and where the status changed more than a year ago.
