JCA type conversion

[rolf <rolf@triumf.ca>]

I am trying to work with Java Channel access (JCA 2.3.2  and CAJ 
1.1.5b). I may have blinders on, but the only documentation I can find 
is the APS tutorial and the JCA javadoc (for JCA 2.1.2). If there is 
anything else, could someone please point me to it.

My specific problem:
I have a MonitorListener, which delivers a MonitorEvent on a PV value 
change.
The MonitorEvent gives me DBR, from which I want to get the new value as 
a String.

My code looks like this:

DBR dbr = evt.getDBR();
DBR dbr2 = dbr.convert(DBRType.CTRL_STRING);
String[] s = ((DBRString) dbr2).getStringValue();

s[0] contains the correct value for all DBR types, with the exception of 
enumerated types, where it has an empty string.
What am I doing wrong?

Thanks - rolf -
