JULovButtonBinding works with a JULovDialogInterface to display LOV
data. An application can pass its own implementation of JULovDialogInterface
in a JULovPanelInterface in order to display an application-specific dialog
instead of the default JULovDialog, which also implements this interface.
Add the LOV binding object to the dialog.
Note that LOV can call helpAction on the LOV binding object.
Add the LOV Panel to dialog display
isOKSelected
boolean isOKSelected()
Return true if the LOV binding should perform
updates of the target row based on this LOV RSI's currentRow.
This method is true by default in JULovDialog, if OK button is pressed.
