Description Alex Nan

Create a time correlation using 2 db serailzied log files. Save the correlation. Restart the workbench. Open the correlation in the log interactions view. Not always but in some cases a NullPointerException is thrown and the correlation cannot be viewed.

A similar problem happens when generating a time correlation from the log view, i.e open a db serialized log file in the log view, right click and choose Correlation by Time:

In 4.5 i5 the following exception occurrs:
 java.lang.NullPointerException

	at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:67)

Note that due to the refactoring work the line of code that fails has changed.
The root cause of the problem is the fact that some CBEs don't have the parent (TRCAgent) set when loaded from the db.

When opening the log interactions view from a monitor or host level the following exception occurrs sometimes:
