2007-08-21 Zhao Shujing <pearly.zhao@oracle.com> * disassembler/DisassemblyWindow.java: Fixes #4672. (fromBox.entryEvent): Use fromSpin.setValue to invoke fromSpin entryEvent. (toBox.entryEvent): Ditto. (refreshList): Change to get next instruction after setValue to model is finished. (rowPrepend): New function. (handleFromSpin): Prepend rows provided by rowPrepend and remove redundant instructions according to the change of memory address. Fixes #4929.
