Using the InfoBurst HTML5 User Interface Preview 1, the following message is displayed when viewing the Cache Queries tab of an existing XDC which contains cache queries:
This Cache is empty .. please run the XDC to build the Cache before adding Cache Queries
This is a known issue in Preview 1 and will be resolved in a future preview. The XDC and cache queries are intact. Simply refresh the XDC to work around the issue.
