These exceptions are the way FG for transition code to notify the caller that something happened to the FG underlying object. But what preventtoraiseObjectMoved, ObjectDeleted in nofityException,notifySuccess? That's not what these methods are for. ObjectMoved and ObjectDeleted are designed to be raised by workflow scripts, during the transition, to inform the workflow machinery that the transition left the object in an unexpected place. notifySuccess marks the end of the transition, and is designed similarly to an event mechanism, to inform interested parties that the transition is complete. If it raises exceptions, then they won't be caught. Florent I.e. DCWorkflowDefinition.notifyCreated swallow ObjectDeleted, ObjectMoved. Why? if ObjectMoved raised in DCWorkflowDefinition.notifyCreated, WorkflowTool.notifyCreated doen`t know about that, and def notifyCreated(self, ob): Notify all applicable workflows that an object has been created and put in its new place. wfs = self.getWorkflowsFor(ob) for wf in wfs: wf.notifyCreated(ob) self._reindexWorkflowVariables(ob) -- ob reindexed in a wrong acquisition wrapper. -- Florent Guillaume, Nuxeo (Paris, France) CTO, Director of RD +33 1 40 33 71 59 http://nuxeo.com [EMAIL PROTECTED] ___ Zope-CMF maillist - Zope-CMF@lists.zope.org http://mail.zope.org/mailman/listinfo/zope-cmf See http://collector.zope.org/CMF for bug reports and feature requests

My object, during change state, move to another folder and should change acqusition wrapper. workflow_tool = getToolByName( my_object, 'portal_workflow') workflow_tool.doActionFor( my_object, 'some_action' ) # during doActionFor raised ObjectMoved but i don`t know about that in here # because WorkflowTool._invokeWithNotification shallow it. # so my_object has old acqusition wrapper. print aq_chain( my_object ) #wrong result __do_something_with_my_object__ my_object.reindexObject() # my_object reindexed on the wrong path ( old # path), but my_object has new physical path :( i think i should subclassing from WorkflowTool and override doActionFor Buthowcan i repaire wrapper? if i create new wrapper in the doActionFor, method namespace has old wrapped object. The call chain looks like: your code - wf_tool.doActdionFor(...) - wf_tool._invokeWithNotification Both of the tool methods return the result of calling the action. In cases where the ObjectMoved exception is raised, the exception has the new object wrappers available, but the tool consumes that part of the information (as you note). Or may be i use WorkflowTool wrongly. Not really; but the tool doesn't expect that you will need reindex the object (it already does that in the new location). Here are a couple of alternate strategies: - You could modify the workflow action's result (which is coming from the code which actually raises the ObjectMoved exception) to include the newly-wrapped object in the result (e.g., as a tuple with the current result). - You could move the code in '__do_something_with_my_object__' into an after script of the workflow, where it would be passed the object in its new wrappers. - You could use the CMFUID tools, and find the object in its new location after running the workflow transition using its UID. Hope that helps, Tres. - -- === Tres Seaver +1 202-558-7113 [EMAIL PROTECTED] Palladion Software Excellence by Designhttp://palladion.com -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDS6dz+gerLs4ltQ4RAu0EAKCM61jP9716FKQ/+LVKOcYdBuPnVwCfXcBg +DtZ/yTwCcSUx72ey8a38jg= =1a2x -END PGP SIGNATURE- ___ Zope-CMF maillist - Zope-CMF@lists.zope.org http://mail.zope.org/mailman/listinfo/zope-cmf See http://collector.zope.org/CMF for bug reports and feature requests
