Hello everybody,

If been using the JdbComboBox component from the dbSwing package, but
get strange results: I have a JdbComboBox bound to a column with a
picklist descriptor attached to anoter dataSet. When the internal
frame, containing the combobox, gets displayed the first time,
everything works fine. The second time the internal frame gets
displayed (notice that the combobox does not get recreated, it is the
same as the first time!), I cannot open my combobox and get an error
something in the sense of:

Exception occurred during event dispatching:

	at java.awt.EventDispatchThread.run(EventDispatchThread.java:68)

Notice that the value 'Nederlands' is the value of the
lookupDisplayColumn from the pickListDescriptor.

So it seems that somehow the combobox gets screwed. When navigating to
another field on the same dataset and trying to change this value, the
combobox picks up the change on the dataset and starts looping between
its datachanged event and updateItemSelected method. This is an
'infinite' loop until the Java VM gets a stack overflow!

Can anyone shed some light on this issue?
Thanks in advance!!
