Manage Pier in Gemstone environment

Ciao, i do some test for use Pier 3.0 into Gemstone 3.1.0.1 environment. I load the 3.0.3 [ConfigurationOfPier3AddOns] and all seems loaded properly. I can work with the Pier Admin Setup for create new pier instance: i configured two pier environment based one to Book Template and one to Blank Template. The *instance work fine. If i work with *instance-admin when i do the login the system answer: a Breakpoint occurred (error 6005), Method breakpoint encountered. - G/S[MonvisoGruppi:1 Seaside Walkback MessageNotUnderstood Remote Debug Proceed Full Stack Possible Causes you sent a message this type of object doesn't understand Stack Trace thisContext WAGemStoneWalkback >> currentContextForWalkback (envId 0) @2 line 3 self aWARemoteDebuggingWalkback initial nil context nil .t1 GsContext .t2 1 thisContext WAGemStoneWalkback >> initializeWithException: (envId 0) @3 line 4 self aWARemoteDebuggingWalkback anException a MessageNotUnderstood occurred (error 2010), a ExecBlock does not understand #'receiver' context nil .t1 aWARemoteDebuggingWalkback thisContext WARemoteDebuggingWalkback >> initializeWithException:continuation: (envId 0) @2 line 3 self aWARemoteDebuggingWalkback anException a MessageNotUnderstood occurred (error 2010), a ExecBlock does not understand #'receiver' aContinuation GsProcess(oop=249109249, status=debug, priority=4, WARemoteDebuggingWalkbackErrorHandler >> open: ( thisContext WARemoteDebuggingWalkback class >> exception:continuation: (envId 0) @3 line 2 self WARemoteDebuggingWalkback anException a MessageNotUnderstood occurred (error 2010), a ExecBlock does not understand #'receiver' aContinuation GsProcess(oop=249109249, status=debug, priority=4, WARemoteDebuggingWalkbackErrorHandler >> open: ( thisContext [] in WARemoteDebuggingWalkbackErrorHandler >> open: (envId 0) @18 line 27 self anExecBlock wb nil logEntry nil continuation GsProcess(oop=249109249, status=debug, priority=4, WARemoteDebuggingWalkbackErrorHandler >> open: ( anException a MessageNotUnderstood occurred (error 2010), a ExecBlock does not understand #'receiver' self aWARemoteDebuggingWalkbackErrorHandler .t1 WARemoteDebuggingWalkback .t2 a MessageNotUnderstood occurred (error 2010), a ExecBlock does not understand #'receiver' .t3 GsProcess(oop=249109249, status=debug, priority=4, WARemoteDebuggingWalkbackErrorHandler >> open: ( The relative GemTools Debug record report : WAErrorHandler >> remoteBreakpointMethod (envId 0) WARemoteDebuggingWalkbackErrorHandler >> open: (envId 0) WADebugErrorHandler >> debugAndResume: (envId 0) WADebugErrorHandler >> handleDefault: (envId 0) WAErrorHandler >> handleError: (envId 0) WAErrorHandler >> handleGemStoneException: (envId 0) WAGemStoneWalkbackErrorHandler >> handleException: (envId 0) [] in WAExceptionHandler >> handleExceptionsDuring: (envId 0) ExecBlock >> on:do: (envId 0) [] in WAExceptionHandler >> handleExceptionsDuring: (envId 0) [] in ExecBlock >> on:do: (envId 0) AbstractException >> _executeHandler: (envId 0) AbstractException >> _signalWith: (envId 0) AbstractException >> signal (envId 0) Object >> doesNotUnderstand: (envId 0) Object >> _doesNotUnderstand:args:envId:reason: (envId 0) Announcer >> subscribe:do: (envId 0) Announcer >> on:do: (envId 0) PRAdminNavigator >> announcementRegister (envId 0) PRAdminAnnouncingComponent >> initialize (envId 0) GRObject class >> new (envId 0) PRAdminUIChild class >> contextGetCallback:contextSetCallback: (envId 0) PRAdminUI >> navigatorComponent (envId 0) PRAdminUI >> children (envId 0) WAPresenter >> childrenDo: (envId 0) WAVisiblePresenterGuide >> visitPresenter: (envId 0) WAPainterVisitor >> visitComponent: (envId 0) WAComponent >> accept: (envId 0) WAVisiblePresenterGuide >> visitDecoration: (envId 0) WADecoration >> accept: (envId 0) WAPainterVisitor >> visitDecorationsOfComponent: (envId 0) WAComponent >> acceptDecorated: (envId 0) WAPresenterGuide >> visit: (envId 0) [] in WAVisiblePresenterGuide >> visitPresenter: (envId 0) [] in WAPresenter >> childrenDo: (envId 0) Collection >> do: (envId 0) WAPresenter >> childrenDo: (envId 0) WAVisiblePresenterGuide >> visitPresenter: (envId 0) WAPainterVisitor >> visitDecoration: (envId 0) WAVisiblePresenterGuide >> visitDecoration: (envId 0) WAPainterVisitor >> visitDelegation: (envId 0) WADelegation >> accept: (envId 0) WAPainterVisitor >> visitDecorationsOfComponent: (envId 0) WAComponent >> acceptDecorated: (envId 0) WAPresenterGuide >> visit: (envId 0) WAVisitor >> start: (envId 0) Thanks for any suggestion, Dario
