Hello all,

 I'm trying to create a Status Object in EPICSv4 with JAVA and I'm using

Status Factory and StatusCreate class. However, in the documentation of

the StatusCreate class says:

/**
	 * Create status.
	 * @param type status type, non-<code>null</code>.
	 * @param message message describing an error, non-<code>null</code>.

 * NOTE: Do NOT use <code>throwable.getMessage()</code> as message,

since it will be supplied with the <code>cause</code>.

	 * @param cause exception that caused an error. Optional.
	 * @return status instance.
	 */
	Status createStatus(StatusType type, String message, Throwable cause);

About creating an status says that parameter Throwable cause it says

it's optional but I can't see how it can be optional. And also, if

status is OK you should not return the status in a catch excepcion

clause, should I? So in that case, status OK how I suppose to have a

Throwable object? Then I should use null in this parameter, am I right?

Thank you very much for your help.

Yours, Ricardo
