1. Frances is debugging an iWidget that should show a loader bar until markup is generated and shown, leveraging only lifecycle functions. Right now, she can only see the loader bar, but nothing else happens in the iWidget. She has verified that all dependencies have loaded properly and that the elements have rendered.

A) Verify that the readyMarkup method is properly implemented.
B) Verify that the onUnload method is properly modifying the page content after loading completes.
C) Verify that the view is a supported mode for the iWidget.
D) Verify the onLoad method kicked off background functions needed to render the markup.

B) He should use the standard Java logger at an "error" level since they are status messages and could be considered errors.
C) He should use the standard Java logger at an "info" level since "info" is the default trace level for IBM WebSphere Portal server.
