Operations tree functions do not perform as expected

A few issues were found when playing with operation list functions in IE9 to see what more expansive operation lists would look like in the browser. These include:

• If an operation is moved below an operation with children, all the children disappear (the root operation remains)
• I had an operation with 3 levels (root, child, then 2 children of the child). I "moved down" one of the 2 children, and it cleared all children, leaving only the root
• Operations cannot be promoted at any level, whether added initially as children, or demoted to become a child
• After performing the above tests in IE9, the operations functions menu became unresponsive and the browser could not contact the running Event Broker service. I was not able to replicate this after performing a far larger test using IE9, however (ie. adding more children, moving and demoting some operations).
