Hi,        my goal is to display Pier environment as Seaside subcomponent.        I have some problem  ....        First i create a class:                        WAComponent subclass: #TestMultiPier                        instanceVariableNames: 'pageA pageB tabs task'                        classVariableNames: ''                        poolDictionaries: ''                        category: 'DTR-TestPier' the                initialize                super initialize.                tabs := OrderedCollection new.                nomeKernel := 'pier'.                pageA := PRPierFrame  on: (PRContext kernel: (PRKernel instanceNamed: nomeKernel )).                self initTopMenuFor the                initTopMenuFor                tabs add: 'PageA' -> pageA. the                renderContentOn: html                html text: 'Prova gestione multi Pier istance'.                html paragraph: Time now.                self renderTopMenuOn: html.                task  ifNotNil:[ html div id: 'divTabMst';                                                with:[ html render: task]] the        renderTopMenuOn: html        html unorderedList id: 'menu'; with: [                tabs do: [ :each |                        html listItem: [                                html anchor                                        class: (task = each value                                                ifTrue: [ 'active' ]);                                        callback: [ task := each value  ];                                        with: each key ] ] ] Now when clic on the PageA link the system rendering the Pier page correctly. The error is erase when i click on sub link   ( of the Pier main page    )      Information or Environment. The system report the error: UndefinedObject(Object)>>doesNotUnderstand: #context: PRCurrentContext class>>value: [] in PRContext>>activationCallback BlockClosure>>valueWithPossibleArguments: WAActionCallback>>evaluateWithArgument: WAActionCallback(WACallback)>>evaluateWithFieldValues: [] in WACallbackRegistry>>handle: OrderedCollection>>do: WACallbackRegistry>>handle: [] in [] in WAActionPhaseContinuation>>runCallbacks BlockClosure>>on:do: WAActionPhaseContinuation(WARenderLoopContinuation)>>withNotificationHandlerDo: [] in WAActionPhaseContinuation>>runCallbacks BlockClosure>>ensure: WAActionPhaseContinuation>>runCallbacks WAActionPhaseContinuation>>handleRequest [] in WAActionPhaseContinuation(WASessionContinuation)>>basicValue BlockClosure>>on:do: WAActionPhaseContinuation(WASessionContinuation)>>withUnregisteredHandlerDo: WAActionPhaseContinuation(WASessionContinuation)>>basicValue Because this ?

Hi, I select        from  /examples/examplebrowser  the      PRPierFrame exampleDocumentation .        When select              PRObject  or   MAObject        link  i found the same error. In my test i found the error :   I d'ont implement  the children method        children        ^ Array with: pageA with it the example work fine. Now i have problem when i have the same seaside application but with reference to  2 different pier site        i change the code to:                nomeKernel := 'anowerpier'.               siteB:= PRPierFrame  on: (PRContext kernel: (PRKernel instanceNamed: nomeKernel )).                tabs add: 'SiteB' -> siteB. With it i d'ont found any very debug problem. The first rendering of siteA and siteB work fine. But when click on link of siteA         i have interference on           siteB. The siteB is update to siteA. Any idea ? I can have more PRPierFrame instances in the same application.
