Lucida GrandeSolved this after trying more things. Here is what I used: # Modify workflow chain (Workflow by type) workflow_tool.manage_changeWorkflows(default_chain='default_workflow', props=({'chain_Image':'image_workflow','chain_Folder':'', 'chain_Topic':''}), REQUEST=None) Regards, David On Saturday, April 9, 2005, at 02:41 PM, David Pratt wrote: I am getting closer: # Modify workflow chain (Workflow by type) workflow_tool.manage_changeWorkflows(default_chain='default_workflow', props=({'name':'chain_Image','value':'image_workflow'}), REQUEST=None) No errors now, but it sets all to Default instead of just the Image.... It seems I am not passing the correct properties. I am getting name and value from the html source of the form. Anyone know what these need to be?

I managed to get my workflow factories installed and then used the manage_addWorkflow to obtain the desired workflow with the appropriate id. Where I am having trouble is changing my default workflow to my new workflow. In the ZMI this would be through the Workflow by Type (the first screen you come into when choosing the portal_workflow tool) once you had built one. For images, if I look at the source for images is 'chain_image' which is set to (Default). I am thinking it is the props should perhaps be a different type but I can't find anything googling that suggest that it is anything but a string. Should it a tuple? The method is manage_changeWorkflows(self, default_chain, props=None, Request=None) This is what I am doing to try and use it: workflow_tool = getToolByName(self, 'portal_workflow') # Modify workflow chain (Workflow by type) workflow_tool.manage_changeWorkflows(default_chain='chain_image', props='image_workflow', REQUEST=None) Here is the traceback: File "/usr/local/zope/instance1/Products/CMFCore/WorkflowTool.py", line 175, in manage_changeWorkflows chain = props.get(field_name, '(Default)').strip() AttributeError: 'str' object has no attribute 'get' It is probably something simple, hope someone can help me with where I am going wrong. Many thanks.
